This directory contains all that you will need in order to get G++
up and running on your system.  The only prerequisite is that you have GNU-C
running on your system before you install G++.  Also, there have been
recent changes and enhancements to the assembler which make it critical that
you have the most recent version.

	The latest gcc-vms.tar.Z from prep.ai.mit.edu contains a compiler
driver which has been patched to work with g++.  This compiler driver has been
extensively reworked, with a number of enhancements and bugfixes, and a number
of new command qualifiers.  If you use the g++ compiler stored here, GCC.COM
will have to be edited, and you should comment out any reference to
vms-collect. The compiler now performs the function that vms-collect provided. 
The patch that gets the compiler to do this is included in gxx-vms.tar.Z

	The file gcc-cc1plus.exe.Z contains a precompiled executable of the
compiler.  This was built from version 1.39 sources; all patches to the sources
are included in gxx-vms.tar.Z

The files libg++.bck.Z and libg++-develop.bck.Z contain all of libg++. If you
are only interested in running libg++, and you are not interested in
recompiling the library, then you will only need libg++.bck.Z.  If you want to
recompile, then you must *also* take libg++-develop.bck.Z.  These distributions
are based upon libg++ 1.37.0.  libg++ 1.39 makes use of the #pragma
interface/#pragma implementation directives which do not work properly in g++
1.39.  These two files are compressed backup save-sets.  These have been 
compressed with a VMS-native mode of compression that saves the file attributes
as well as the file.  This is done so that once the file has been decompressed
the record size will be correct, and backup can be used with no further
processing.  You will *not* be able to decompress these files on a unix system.

	The file gxx-vms.tar.Z contains the patches that were applied to the
sources before the executable in gcc-cc1plus.exe.Z was built.  It also contains
other files which are of use *only* if you do not plan to use libg++.

	The file gas-1.38.1.diff contains a patch which fixes a bug with static
constants.  You will *only* need to use this if you plan to rebuild the
assembler from the sources.  The binaries in gcc-vms.tar.Z already have this
patch.

	The large files in this directory have been LZ-Compressed to save
network bandwidth.  These files all have a ".Z" at the end of their filenames.
Naturally they should be transferred in image mode.  With the exception of
libg++, these files can be unpacked on unix or VMS.  If unpacked on VMS, use
the "/mode=bin/export=noend" qualifiers with the decompressor.

	A copy of LZDCMP.EXE (uncompressed) for VMS systems has also been
provided.  Usage is:
$decompress:==$ddcu:[dir]LZDCMP
$decompress file.tz file.tar
