$! BUILD_VMS.COM
$!
$! I've taken the original build_vms.com, supplied by Nico Baggus, if
$! memory serves me correctly, and made some modifications.
$!
$! SSL support is controlled by logical names.  If SSL$INCLUDE is
$! defined, then it is assumed that HP's SSL product has been installed.
$! If OPENSSL is defined, but SSL$INCLUDE is not, then OpenSSL will be
$! used.  If neither logical name is defined, then SSL support will not
$! be compiled/linked in.  Command-line options NOHPSSL and NOSSL can be
$! specified to override the automatic SSL selection.
$!
$! Command-line Options:
$!
$!    CLEAN     Delete product files for this host architecture.  (No
$!              build done.)
$!    CLEAN_ALL Delete product files for all host architectures.  (No
$!              build done.)
$!
$!    64        Compile with 64-bit pointers.
$!    CCQUAL=x  Add "x" to the C compiler qualifiers.
$!    DEBUG     Compile and link with debug.
$!    IEEE      Use IEEE floating point.  (Alpha.)
$!    LARGE     Enable large-file support.  (Non-VAX, VMS >= V7.2.)
$!    LDAP      Enable LDAP support.
$!    LIST      Create C compiler listings and linker maps.
$!    NOHPSSL   Don't use HP SSL, even if available.
$!    NOSSL     Don't use any SSL, even if available.
$!    OSSLOLB   Use OpenSSL object libraries (.OLB), even if shared
$!              images (.EXE) are available.
$!
$! DCL Symbols:
$!
$!    CURL_CCDEFS="c_macro_1=value1 [, c_macro_2=value2 [...]]"
$!              Compile with these additional C macros defined.
$!
$! Revisions:
$!
$!  2-DEC-2003, MSK, the "original" version.
$!                   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 dependent 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 curl_config.h.
$! 15-MAR-2004, MSK, All of the curlmsg*.* files have also been moved to
$!                   this build directory.  They will be copied to the src
$!                   directory before build.  The .msg file will be compiled
$!                   to get the .obj for messages, but the .h and .sdl files
$!                   are not automatically created since they partly rely on
$!                   the freeware SDL tool.
$!  8-FEB-2005, MSK, merged the two config-vms.h* files into one that uses
$!                   USE_SSLEAY to define if the target has SSL support built
$!                   in.  Changed the cc/define parameter accordingly.
$! 11-FEB-2005, MSK, If [--.LIB]AMIGAOS.C and NWLIB.C are there, rename them
$! 23-MAR-2005, MSK, relocated cc_qual define so that DEBUG option would work
$! 25-APR-2007, STL, allow compilation in 64-bit mode.
$! 13-DEC-2009. SMS, Changed to skip unwanted source files without
$!                   renaming the original files.
$!                   Eliminated needless, persistent logical names.
$!                   Added CURL_CCDEFS DCL symbol for user-specified C
$!                   macro definitions.
$!                   Added CLEAN and CLEAN_ALL options.
$!                   Added CCQUAL option for user-specified C compiler
$!                   qualifiers.
$!                   Added IEEE option for IEEE floating point (Alpha).
$!                   Added LARGE option for large-file support.
$!                   Added OSSLOLB option, and support for OpenSSL
$!                   shared images.
$!                   Changed to put listing and map files into lisdir:.
$!                   Changed to avoid case confusion on ODS5 disks.
$!                   Added more default dev:[dir] save+restore.
$!                   Moved remaining "defines.com" code (back) into
$!                   here, eliminating the hard-coded OpenSSL nonsense.
$!                   Changed to use F$GETSYI( "ARCH_NAME") (or
$!                   equivalent) to name architecture-specific product
$!                   file destination directory, and to create the
$!                   directory if needed (obviating inclusion of these
$!                   directories and dummy files in the distribution
$!                   kit).
$!                   Changed the "compile" subroutine to break the CC
$!                   command across multiple lines to avoid DCL
$!                   line-too-long problems.
$!                   Changed "vo_c" messages to show the CC qualifiers
$!                   once, not with every compile command.
$!
$!
$! Save the original default dev:[dir], and arrange for its restoration
$! at exit.
