The -ansi and -std=iso9899:199409 somehow confused AIX's standards.h file.  I notice that _ALL_SOURCE_ is (re)defined in config.h.

It is the -ansi flag I believe that is doing the harm.  Removing that gets the file to compile.  Adding that in causes standards.h to *not* define _POSIX_SOURCE_ and that leads to ulong_t (and other typedefs) not being defined.

AIX version is 6.1 TL07 SP03.  GCC is 4.5.2
