-dnl Look for the initgroups() declaration.  On AIX 4.[13], Solaris 4.1.3, and
-dnl ULTRIX 4.2A the function is defined in libc but there's no declaration in
-dnl any system header.  
-dnl
-dnl On Solaris 2.[456], the declaration is in <grp.h>.  On HP-UX 9-11 and
-dnl (reportedly) FreeBSD 3.[23], it's in <unistd.h>.  Any other locations we
-dnl need to check?

-dnl On AIX 4.1, snprintf() is defined in libc.a but there's no prototype in
-dnl <stdio.h> or elsewhere.  Apparently it's not officially supported (though it
-dnl seems to work perfectly and IBM apparently uses it in internal code).
-dnl Anyhow, if we omit our own snprintf() and vsnprintf() prototypes when we
-dnl HAVE_SNPRINTF, we get a billion warnings at compile time.  Use the C
-dnl preprocessor to preprocess stdio.h and make sure that there's actually a 
-dnl prototype.
