$! File: config_h.com
$!
$! This procedure attempts to figure out how to build a config.h file
$! for the current project.
$!
$! P1 specifies the config.h.in file or equivalent.  If it is not specified
$! then this procedure will search for several common names of the file.
$!
$! The CONFIGURE shell script will be examined for hints and a few symbols
$! but most of the tests will not produce valid results on OpenVMS.  Some
$! will produce false positives and some will produce false negatives.
$!
$! It is easier to just read the config.h_in file and make up tests based
$! on what is in it!
$!
$! This file will create an empty config_vms.h file if one does not exist.
$! The config_vms.h is intended for manual edits to handle things that
$! this procedure can not.
$!
$! The config_vms.h will be invoked by the resulting config.h file.
$!
$! This procedure knows about the DEC C RTL on the system it is on.
$! Future versions may be handle the GNV, the OpenVMS porting library,
$! and others.
$!
$! This procedure may not guess the options correctly for all architectures,
$! and is a work in progress.
