dnl Process this file with autoconf to produce a configure script.

dnl Checks for header files.

dnl The check on dynamically loaded modules requires the building of
dnl something to load. This seems to be something that varies between
dnl systems and compilers something awful. Therefore, we enable it only

dnl I tried using AC_CANONICAL_HOST, but it insisted on looking for an
dnl "install" script for some weird reason.
