Bug#565708: gcc-4.4: -D_XOPEN_SOURCE=600 does not make strcasecmp visible

[John Lindgren <john.lindgren@tds.net>]

Package: gcc-4.4
Version: 4.4.2-8
Severity: normal

SUSV3 lists strcasecmp() as an XSI extension, so it should be enabled by
setting _XOPEN_SOURCE to 600 before including string.h.  In GCC it is
not unless _BSD_SOURCE is also defined.

Test program:

        #include <string.h>
        
        int main (void)
        {
            return strcasecmp ("hello", "world");
        }
        
Compile results:

        $ gcc -std=c99 -D_XOPEN_SOURCE=600 test.c
        test.c: In function ‘main’:
        test.c:5: warning: implicit declaration of function ‘strcasecmp’
        $ gcc -std=c99 -D_XOPEN_SOURCE=600 -D_BSD_SOURCE test.c
