XFree86 - weird warnings

[chris at loconet.org]

when installing an updated version of x11 i get the following warning
which i never gotten befor.

/usr/include/sys/cdefs.h:163:51: warning: "__STDC_VERSION__" is not
defined
/usr/include/sys/cdefs.h:174:5: warning: "__STDC_VERSION__" is not defined
/usr/include/sys/cdefs.h:326:5: warning: "_POSIX_C_SOURCE" is not defined
/usr/include/sys/cdefs.h:332:5: warning: "_POSIX_C_SOURCE" is not defined

isnt something that kills the port but sure as hell is anoying on every
source file to have that heh
