Problems with 3.7p1 on IRIX 6.5

[Ayamura KIKUCHI]

> It works if I define BROKEN_GETADDRINFO, SETEUID_BREAKS_SETUID,
> BROKEN_SETREUID, and BROKEN_SETREGID.

required macro preprocessors for IRIX 6.5.21:
	SETEUID_BREAKS_SETUID/BROKEN_SETREUID/BROKEN_SETREGID
no required:
	BROKEN_GETADDRINFO/BROKEN_INET_NTOA
