Programmer error.  Either it's a C99 program or it's an old-POSIX
program; it cannot be both.

> #define _GNU_SOURCE  1
> #define _ISOC99_SOURCE  1
> #define _POSIX_C_SOURCE  199506L
> #define _XOPEN_SOURCE  500
> #define _LARGEFILE64_SOURCE  1

It is requesting contradictory namespaces, and getting what it
deserves.  It should not define any of these.
