$! BUILD_VMS.COM 
$!
$! I've taken the original build_vms.com, supplied by Nico Baggus, if
$! memory serves me correctly, and made some modifications.
$!
$! SSL support is based on logicals, or lack thereof.  If SSL$INCLUDE
$! is defined, then it assumed that hp's SSL product has been installed.
$! If OPENSSL is defined, but SSL$INCLUDE isn't, then the OpenSSL defined
$! via the defines.com procedure will be used.  If neither logical is 
$! defined, then SSL support will not be compiled/linked in.
$!
$! If CURL_BUILD_NOSSL is defined to anything, then no SSL support will
$! be built in.  This way you can build without SSL support on systems
$! that have it without the "automatic" build/link "features".
$!
$! If CURL_BUILD_NOHPSSL is defined to anything, it will override the
$! SSL$INCLUDE check.  This way you can build against OpenSSL, even if
$! you have hp SSL installed.
$!
$! Parameter(s):
$!
$! P1 - LISTING will create .lis files during the C compile
$!      DEBUG will compile and link with debug
$!
$! Revisions:
$!
$!  2-DEC-2003, MSK, the "original" version. <marty@barra.com>
$!                   It works for me.  Your mileage may vary.
$! 13-JAN-2004, MSK, moved this procedure to the [.packages.vms] directory
$!                   and updated it to do hardware dependant builds.
$! 29-JAN-2004, MSK, moved logical defines into defines.com
$!  6-FEB-2004, MSK, put in various SSL support bits
$!  9-MAR-2004, MSK, the config-vms.h* files are now copied to the lib and
$!                   src directories as config.h.
