Subject: (AC_PREREQ): Bump from 2.50 to 2.51; needed for vfork.
X-Git-Tag: ttn-vms-21-2-B4~17875
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=5a129fafb5d7c3fb8cc7be7e03fe1444a97919cf;p=emacs.git

(AC_PREREQ): Bump from 2.50 to 2.51; needed for vfork.
(AC_FUNC_VFORK): Remove.
(AC_FUNC_FORK): Add.
(HAVE_DES_H, HAVE_KRB5_H): Properly quote args of AC_CHECK_HEADERS;
this is required by recent Autoconf versions.
