I opened PR 55384 to track this

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55384

The problem is AIX stdlib.h defines

#define vec_free free

and vec.h

defines two functions named vec_free()

With the VEC changes, these now are renamed "free" and lead to
ambiguous name resolution.

I am not sure where

#undef vec_free

should be placed.  In vec.h or system.h?

Thanks, David
