Unless you do it cleanly and push the changes upstream?
glibc does this in the upstream headers, so why couldn't other
packages do that as well?

If the only differences are wordsize related, you can e.g.
portably #include <limits.h> and do:
#if LONG_MAX == 2147483647L
32-bit stuff
#else if LONG_MAX == 9223372036854775807L
64-bit stuff
#else
#error Unsupported long size
#endif
etc.
