This patch adds some missing default ISO C++ headers to SimGear, especially usefull for Irix/MipsPro. To the best of my knowledge this only affects the Irix/MipsPro compiler combination although it might be usefull for others as well. This patch does not yet remove any compiler specific code, but that would be my next task. The powerfull macros as defined in the compiler.h file allowed me to split it up into multiple patches.

/** \file compiler.h
|
|
* 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.
|
|
*
|
|
* (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>.
