* tests/uid.c (main): Ignore uids returned by getresuid to avoid 16bit vs 32bit issues on big endian architectures. Change real UID instead of effective UID in setresuid test. * tests/uid16.c (main): Likewise. * tests/uid32.c (main): Change real UID instead of effective UID in setresuid test to match uid.c * tests/uid.awk: Update setresuid regexp.
