Perhaps what Pascal was remembering is the "Visual Ada" product
trademarked and sold by Aetech in the 1993-1994 time frame.  This Visual
Ada was an option for Aetech's IntegrAda for Windows product.  It was a
GUI builder very similar in appearance to the one in Microsoft's  Visual
Basic 1.0.  I bought 20 copies to use for an Ada class at Holloman AFB,
NM in 1994. 

See IntegrAda for Windows, Version 1.2 in
http://sw-eng.falls-church.va.us/ajpo_databases/ada83_validated_compilers.html

Apparently Aetech has been out of business for some time. They used to
have a Web site at www.pcada.com but it is no longer active.

Yes, Aetech has been gone for quite a while. After their demise, one of
their former employees ended up with the software. We (RR Software)
licensed the programming environment from him, and renamed it JAWS II.
It's still found in Janus/Ada, although it is unmaintainable (because we
didn't get the source code, and apparently no one has it anymore). We're
working on replacing it with a Claw program.

I didn't know there was a Visual C++ for Linux.

Linux is a little harder than Windows because there are so many
different hardware architectures to support.

Moreover Visual C++ is not so "visual" as it announce itself :-)

Actually, several Free Software projects have reported that release of 
a
new version was delayed by porting the product to M$-Vindows. :=)

Further, if you are not diddling with the hardware (as you shouldn't 
be),
then porting to *any* version of X/Linux from *any* other should be no
harder than copying the package (as in distro) to the desired platform
and typing "make". X and Linux worry about the architecture.

If you're writing a compiler, you have to.

Huh?  I've never seen a compiler that performs direct hardware access.
Compilers are usually the most portable pieces of software in common
use because they only translate one text file to another.  Porting
compilers to a new host is usually not very hard (however, adding a
new target is a completely different story ;).

A lot of software which has been developed on a GNU/Linux system
assumes a little-endian machine with pointers and C ints which are 32
bits wide, and that the hardware does not require any alignment for
the standard types.

A lot of software? Pretty much anything shipped with Debian or RedHat has
been compiled and probably run on Alphas and other architectures.

This is just a fraction in comparison to what is announced via
channels like Freshmeat.

But it's a large fraction, and more important, it's one selected (at least
on Debian) for the property of being interesting. The original quote was
"if _you_ are not diddling with the hardware ... then porting to *any*
version of X/Linux from *any* other _should_ be no harder than copying
the package ... to the desired platform and typing 'make'." (Underlines mine.)
The fact that some beginning programmers rewriting some basic project make
elementary mistakes (that would happen on any platform, and any low-level
language like C or Ada) does not mean that you should make them.

It does not neccessarily mean that the software work in 64 bit mode. Many, if
not all 64 bit machines support a 32 bit pointer environment with 32 bit
integers.

Debian does not compile its Alpha packages in that mode. (I don't believe
an Alpha has that mode, or even if it does, that GCC for the alpha-linux-gnu
supports using it. So I doubt Red Hat uses it either.)

Alpha has no 32 bit addressing mode in hardware.  A compiler that
is going to use 32 bit pointers will generate code that sign-extends
the 32 bit pointer when loading it into a 64-bit register.

A standard editbox has a 32K limit (son of Windows 3.1); a "rich edit"
control has a 4G limit, and a whole bunch of different problems... ;-)
