This was created for testing my patch for C++ perl modules. It runs with
dynamic and static extensions under OS/2.

It should work with gcc and dynamic build out of the box. With other 
compilers you should find a different mean to convince MakeMaker to 
compile the file as C++. With gcc I just put '-x c++' into INC (yuck ;-)
of Makefile.PL. Try to peruse different buttons of MakeMaker.

The patch is in the file `patch'.

After the patch is applied you can compile perlmain.c with C++ compiler
and use it with static and dynamic C++ modules. You may force 
a particular way of perl compile in build directory by editing the
corresponding line in `cflags', similar to this (for gcc):

    perlmain) cc="$cc -x c++";;

It is possible to build static C++ extensions, probably something like what is
below (CC=CC on 'make' line) should work. With gcc you do it like this:

make static
make perlmain.o CC="gcc -x c++"
make perl

(if on OS/2, substitute `make perlmain.obj').

Dynamic build of example C++ extension:

Apply patch, remake perl, install it (or copy h2xs, xsubpp and all other 
relevant files (like Miniperl.pm) to appropriate locations). Do this in
perl build directory:

patch < ...../patch
sh writemain.SH
make
make test
make install

Keep in mind that perlmain.c is autogenerated by writemain that is
autogenerated by writemain.SH, but the last rule is not in makefiles.
Similarly with Miniperl.pm and minimod.PL, but this time the rule is
there. The above sequence most probably does all the black magic ;-0.

Then run

perl Makefile.PL
make
make test

If you do not have gcc, probably you should run something like

make CC=CC INC=
