The first version of gcc for OS/2 that I installed from the Hobbes CD
was gcc2.  Mention has been made that it lacks a debugger and other
tools.  However, it seems to be well documented, and it does have good
tools for examining the libraries.

I tried some number crunching programs that had compiled under the
Borland compiler (MSWindows version), and had some difficulties.
Since I have a 486DX, I had most variables declared as 'long double',
but this was not supported by gcc2.  After minor editing, I ran the
compiler, but I must have been missing something: error messages were
generated that I recall as claiming that there was an error connected
with some symbol declared in one of the library routines.  I have seen
no other mention of this difficulty in this newsgroup (except for
hints that the implementation was a little "buggy"), and I stopped
using gcc2 after discovering the emx version.

The few experiments I have tried with emx/gcc seem to have worked, but
I have not had the time to do much nor the need to produce any new
programs. Everything had text based I/O -- I haven't looked into PM
programming.  Comments in this newsgroup have not been clear whether
the libraries provide complete support for PM programming.

Commercial compilers offer me too little to justify their price, so I
expect to rely on gcc (and REXX) for any programming needs.  I have
been browsing this group, and have seen some helpful comments, but I
don't recall seeing a FAQ.
