Re: AC_FUNC_GETMNTENT look in libc before -lsun

[Paul Eggert]

Thanks.  I installed this slightly-different patch for the UNICOS problem.
Bob Proulx has graciously volunteered to look into fixing the web pages.

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.
