File: autoconf.info, Node: Preprocessor Symbol Index, Next: Cache Variable Index, Prev: Output Variable Index, Up: Indices B.3 Preprocessor Symbol Index ============================= This is an alphabetical list of the C preprocessor symbols that the Autoconf macros define. To work with Autoconf, C source code needs to use these names in ‘#if’ or ‘#ifdef’ directives. * Menu: * __CHAR_UNSIGNED__: C Compiler. (line 284) * __EXTENSIONS__: C and Posix Variants.
