I can see definite cases where it could be useful in glibc headers, to redirect functions to the appropriate version for a particular standard in the implicitly preincluded stdc-predef.h even if the header declaring the function in question isn't included (ISO C and POSIX allow you to declare standard functions yourself if the standard prototype for the function doesn't involve any type defined in a header). So, I think it's quite right for it to be available on all platforms as a feature that can help in implementing certain standard requirements. -- Joseph S. Myers jos...@codesourcery.com
