This isn't portable in any way. This is probably not the right way to
do this.
The portable way to do this would be something like:
#include <limits.h>
#if ULONG_MAX > 0xffffffffUL
# define ELF_BITS 64
#else
# define ELF_BITS 32
#endif
There is also the option of looking for either __LP64__ or __ILP32__
which isn't 100% portable but works with all newer versions of gcc:
#ifndef ELF_BITS
# ifdef __LP64__
# define ELF_BITS 64
# elif defined(__ILP32__)
# define ELF_BITS 32
# else
# error "Unknown size, please define ELF_BITS"
# endif
#endif
... or something like that.
