That didn't work when cross-compiling. Simply rely on limits.h.
If a compiler does not have limits.h, then zconf.h.in should be
modified to define Z_U4 as an unsiged four-byte integer type in
order for crc32() to be fast.
This also simplifies and makes more portable to check for a four-
byte type using limits.h.
