Enclosed are the patches for g++ 1.39.0 on VMS.  The first step should be for
you to upgrade GCC with the gcc-vms.tar.Z binaries package available on
prep.ai.mit.edu. The compiler driver, preprocessor, and assembler have all of
the required patches to be used with g++ 1.39.0. These files also contain all
of the patches required for libg++ 1.37.1.

There are compiler bugs in the g++ #pragma implementation/interface in version
1.39.0, which prevent successful compilation of libg++ 1.39.0.  Version 1.37.1
of libg++ does not use these directives, and should work correctly. 

g++ 1.39 uses a slightly different convention for telling a destructor whether
the memory needs to be deallocated or not (i.e. was it malloced or not), so
libraries compiled with 1.37.1 or earlier should be recompiled.

I have also upgraded the gcc-cc1plus.exe on mango.miami.edu for those that
don't wish to build the compiler themselves. makefile.vms and make-cc1plus.com
have also been upgraded to reflect new source files in g++ 1.39.0. 

There are three patches to the compiler supplied here.  These are all relatively
minor changes, and they are all described in the [.cc1plus]readme. file.

The file tm-vms.h in the GCC sources now contains the line:

#define NO_DOLLAR_IN_LABEL

This fixes the problem where the compiler complains about variables that start
with a dollar sign (e.g. the $$PsectAttribute hack for stdin, stdout, stderr).
