You also, unfortunately, can't use it at include time because it's defined in a 
header and not by the compiler, so it isn't defined until after you include 
something from glibc, and by this time glibc has defined a load of internal 
macros based on the standards macros that you define.  You'd need a configure 
script that checked for glibc and defined something in common.h for glibc.
