MSVC fix: deambiguiate function calls

Allow complex animation expressions

Example: translate along the y-axis following a sin
function.
<animation>
  <type>translate</type>
  <axis>
    <y>1</y>
  </axis>
  <expression>
    <sin>
      <product>
        <property>/some/position-norm</property>
        <value>6.28</value>
      </product>
    </sin>
  </expression>
</animation>

-This document describes how to build SimGear using the supplied workspace and
-project files.  
-
-Unpack the SimGear source file into your work directory.  This creates a new
-subdirectory called SimGear-X.Y.Z.  Rename this to SimGear.  Before we can
-build SimGear you must unpack and build the third party libraries metakit and
-zlib.  Sources for these are included in the SimGear/src-libs directory.
-Unpack these into the top level SimGear directory.  At this point your
-directory structure should look something like this:
-
-<work_dir>/
-  SimGear/
-    metakit-x.y.z/
-    simgear/
-    src-libs/
-    zlib-x.y.z/
-
-Now open the SimGear workspace.  This workspace file contains projects for
-building metakit(mklib), SimGear and zlib.  Select each project as the active
-project and build all.  Order is unimportant since there are no dependencies
-between the projects.
-
-The workspace and project files are generated by a perl script with extra
-input from the am2dsp.cfg file.

+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt and /opt/local and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST
+#

  * A set of defines to encapsulate compiler and platform differences.
  * Please refer to the source code for full documentation on this file.
  *
- * Here is a summary of what this file does.
+ * This file is useful to set compiler-specific options in every file - for
+ * example, disabling warnings.
  *
- *  (1)  Defines macros for some STL includes which may be affected
- *       by file name length limitations.
- *
- *  (2)  Defines macros for some features not supported by all C++ compilers.
- *
- *  (3)  Defines 'explicit' as a null macro if the compiler doesn't support
- *       the explicit keyword.
- *
- *  (4)  Defines 'typename' as a null macro if the compiler doesn't support
- *       the typename keyword.
- *
- *  (5)  Defines bool, true and false if the compiler doesn't do so.
- *
- *  (6)  Defines SG_EXPLICIT_FUNCTION_TMPL_ARGS if the compiler
- *       supports calling a function template by providing its template
- *       arguments explicitly.
- *
- *  (7)  Defines SG_NEED_AUTO_PTR if STL doesn't provide auto_ptr<>.
- *
- *  (8)  Defines SG_NO_ARROW_OPERATOR if the compiler is unable
- *       to support operator->() for iterators.
- *
- *  (9)  Defines SG_USE_EXCEPTIONS if the compiler supports exceptions.
- *       Note: no FlightGear code uses exceptions.
- *
- *  (10) Define SG_NAMESPACES if the compiler supports namespaces.
- *
- *  (11) SG_MATH_FN_IN_NAMESPACE_STD -- not used??
- *
- *  (12) Define SG_HAVE_STD if std namespace is supported.
- *
- *  (13) Defines SG_CLASS_PARTIAL_SPECIALIZATION if the compiler 
- *       supports partial specialization of class templates.
- *
- *  (14) Defines SG_HAVE_STD_INCLUDES to use ISO C++ Standard headers.
- *
- *  (15) Defines SG_HAVE_STREAMBUF if <streambuf> of <streambuf.h> are present.
- *
- *  (16) Define SG_MATH_EXCEPTION_CLASH if math.h defines an exception class
- *       that clashes with the one defined in <stdexcept>.

+
+/****
+* NAME
+*   netBuffer - network buffer class
+*
+* DESCRIPTION
+*   Clients and servers built on top of netBufferChannel
+*   automatically support pipelining.
+*
+*   Pipelining refers to a protocol capability. Normally,
+*   a conversation with a server has a back-and-forth
+*   quality to it.  The client sends a command, and
+*   waits for the response. If a client needs to send
+*   many commands over a high-latency connection,
+*   waiting for each response can take a long time. 
+*
+*   For example, when sending a mail message to many recipients
+*   with SMTP, the client will send a series of RCPT commands, one
+*   for each recipient. For each of these commands, the server will
+*   send back a reply indicating whether the mailbox specified is
+*   valid. If you want to send a message to several hundred recipients,
+*   this can be rather tedious if the round-trip time for each command
+*   is long. You'd like to be able to send a bunch of RCPT commands
+*   in one batch, and then count off the responses to them as they come. 
+*
+*   I have a favorite visual when explaining the advantages of
+*   pipelining. Imagine each request to the server is a boxcar on a train.
+*   The client is in Los Angeles, and the server is in New York.
+*   Pipelining lets you hook all your cars in one long chain; send
+*   them to New York, where they are filled and sent back to you.
+*   Without pipelining you have to send one car at a time. 
+*
+*   Not all protocols allow pipelining. Not all servers support it;
+*   Sendmail, for example, does not support pipelining because it tends
+*   to fork unpredictably, leaving buffered data in a questionable state.
+*   A recent extension to the SMTP protocol allows a server to specify
+*   whether it supports pipelining. HTTP/1.1 explicitly requires that
+*   a server support pipelining. 
+*
+* NOTES
+*   When a user passes in a buffer object, it belongs to
+*   the user.  When the library gives a buffer to the user,
+*   the user should copy it.

+/****
+* NAME
+*   netChannel - network channel class
+*
+* DESCRIPTION
+*   netChannel is adds event-handling to the low-level
+*   netSocket class.  Otherwise, it can be treated as
+*   a normal non-blocking socket object.
+*
+*   The direct interface between the netPoll() loop and
+*   the channel object are the handleReadEvent and
+*   handleWriteEvent methods. These are called
+*   whenever a channel object 'fires' that event.
+*
+*   The firing of these low-level events can tell us whether
+*   certain higher-level events have taken place, depending on
+*   the timing and state of the connection.
+*

+/****
+* NAME
+*   netChat - network chat class
+*
+* DESCRIPTION
+*   This class adds support for 'chat' style protocols -
+*   where one side sends a 'command', and the other sends
+*   a response (examples would be the common internet
+*   protocols - smtp, nntp, ftp, etc..).
+*
+*   The handle_buffer_read() method looks at the input
+*   stream for the current 'terminator' (usually '\r\n'
+*   for single-line responses, '\r\n.\r\n' for multi-line
+*   output), calling found_terminator() on its receipt.
+*
+* EXAMPLE
+*   Say you build an nntp client using this class.
+*   At the start of the connection, you'll have
+*   terminator set to '\r\n', in order to process
+*   the single-line greeting.  Just before issuing a
+*   'LIST' command you'll set it to '\r\n.\r\n'.
+*   The output of the LIST command will be accumulated
+*   (using your own 'collect_incoming_data' method)
+*   up to the terminator, and then control will be
+*   returned to you - by calling your found_terminator()
