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