$! File: GENERATE_CONFIG_H_CURL.COM
$!
$! Curl like most open source products uses a variant of a config.h file.
$! Depending on the curl version, this could be config.h or curl_config.h.
$!
$! For GNV based builds, the configure script is run and that produces
$! a [curl_]config.h file. Configure scripts on VMS generally do not
$! know how to do everything, so there is also a [-.lib]config-vms.h file
$! that has VMS specific code that compensates for bugs in some of the
$! VMS shared images.
$!
$! This generates a [curl_]config.h file and also a config_vms.h file,
$! which is used to supplement that file. Note that the config_vms.h file
$! and the [.lib]config-vms.h file do two different tasks and that the
$! filenames are slightly different.
