FreeBSD has them.  According to its man pages, getuid was introduced in 
Version 7 AT&T Unix.  Ancient history.  It doesn't say when getgid was 
introduced, but it's just as old as it's documented in my 1980 edition 
Berkeley VAX UNIX manual, and in any case both are in POSIX.1 and 
therefore ought to be portable by definition.
