From "(libc) Feature Test Macros": You should define these macros by using `#define' preprocessor directives at the top of your source code files. These directives _must_ come before any `#include' of a system header file. It is best to make them the very first thing in the file, preceded only by comments. You could also use the `-D' option to GCC, but it's better if you make the source files indicate their own meaning in a self-contained way. ... - Macro: _GNU_SOURCE If you define this macro, everything is included: ISO C89, ISO C99, POSIX.1, POSIX.2, BSD, SVID, X/Open, LFS, and GNU extensions. In the cases where POSIX.1 conflicts with BSD, the POSIX definitions take precedence. 2004-09-24 Jim Blandy * samples/async.c: #define _GNU_SOURCE before #including any files, to get prototypes for GNU-specific functions like strsignal.
