/*
* This header is included for alignment with the ISO/IEC 9899:1999 standard.
* The contents are only visible when using a c99 compiler. In the case of
* the Sun compiler, some C99 features, including the _Bool built-in type,
* are provided in the default compilation mode. This is a subset of what
* is provided when __STDC_VERSION__ is 199901; hence the contents of this
* header are made visible when either __STDC_VERSION__ >= 199901 (_STDC_C99
* as defined in sys/feature_tests.h) or if __C99FEATURES__ (a Sun compiler
* built-in) is defined. Likewise for GNU C, support for C99 features,
* including this header, is provided in versions 3.0 or greater. In no
* case should the contents of this header be visible in a C++ build
* environment.
*
* Note that the ability to undefine and redefine the macros bool,
* true, and false is an obsolescent feature which may be withdrawn
* in a future version of the standards specifications.
