Subject: Add custom version of AC_CHECK_LIB that uses the extra libs in the
X-Git-Tag: SUDO_1_7_9~19
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a0200118384b5856a8c1a523f4736a948dec7e3d;p=sudo

Add custom version of AC_CHECK_LIB that uses the extra libs in the
cache value name.  With this we no longer need to rely on a modified
version of autoconf.
