Below are the minimum required patches to InterViews 3.1 beta2 so that
it can be compiled with other implementations of C++, notably g++.

It seems that stdio.h is not required to be included by any of the
typical .h files, so one must explicitly include it.

One cannot use operator delete to delete a const pointer, namely this
that points to a const object, shame on your compiler for not throwing
fits when you tried to do that!  Mine does.  :-)

Make sure getwd is declared...

g++ no longer needs the size hint to delete [].

Make sure read is declared (it can be found in unistd.h in ALL g++
implementations because libg++ has a unistd.h header file).

Realize that #ifdef __GNUC__ won't work in that context, because
/lib/cpp is used, not g++ -E or some such.

Also, the RPC classes won't work out of the box with libg++, yet.

All of these patches should go into the official 3.1 release, with the
exception of the last two.  I provide them to illustrate the
limitation of not being able to ask if the compiler is g++ in the
local.def file and for completeness, if you want to compiler using
g++.

Note, so far I have only done a first pass test as this stuff, I have
yet to run any of the a.out generated to verify proper functionality.
All I know is that all software compiles.


					Happy Hacking,

I leave on open offer to fix bugs people find in g++ that prevents it
from being able to correctly compile all of InterViews 3.1 beta (or
beta2).  Feel free to send detailed bug reports directly to me.  (Note,
saying ibuild core dumped the second time through is not helpful
enough for me to fix any specific problem.)
