$! BUILDBZ2.COM
$!
$! Build procedure for LIBBZ2_NS support library used with the
$! VMS versions of UnZip/ZipInfo and UnZipSFX
$!
$! Last revised: 2007-12-29 CS.
$!
$! Command args:
$! - select compiler environment: "VAXC", "DECC", "GNUC"
$! - select compiler listings: "LIST" Note that the whole argument
$! is added to the compiler command, so more elaborate options
$! like "LIST/SHOW=ALL" (quoted or space-free) may be specified.
$! - supply additional compiler options: "CCOPTS=xxx" Allows the
$! user to add compiler command options like /ARCHITECTURE or
$! /[NO]OPTIMIZE. For example, CCOPTS=/ARCH=HOST/OPTI=TUNE=HOST
$! or CCOPTS=/DEBUG/NOOPTI. These options must be quoted or
$! space-free.
$!
$! To specify additional options, define the symbol LOCAL_BZIP2
$! as a comma-separated list of the C macros to be defined, and
$! then run BUILDBZ2.COM. For example:
$!
$! $ LOCAL_BZIP2 = "RETURN_CODES"
$! $ @ []BUILDBZ2.COM
$!
$! If you edit this procedure to set LOCAL_BZIP2 here, be sure to
$! use only one "=", to avoid affecting other procedures.
$!
