dnl     This file is an input file used by the GNU "autoconf" program to
dnl     generate the file "configure", which is run during the build
dnl     to configure the system for the local environment.

# This file and the script it generates is used by both the devkit
# and the Perl FCGI module.  Although each has slightly different
# requirements, this allows the build environment to maintained by one
# file set.  The FCGI build is idendified by the presence of the
# file FCGI.XL.  If its not found, its consider a devkit build.
