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. Jakub
