Re: AC_FUNC_GETMNTENT look in libc before -lsun

[Paul Eggert]

Sorry, my previous patch wasn't correct since it didn't set the
cache vars people expect.  I installed this instead:

2004-12-06  Paul Eggert  <address@hidden>

        * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
        looking elsewhere for getmntent.  Problem reported by Mark D. Baushke.
        * doc/autoconf.texi (Particular Functions): Mention new behavior.
