Sounds good. I haven't looked at the current version (I'll wait for the
new version; make sure it gets into the Fernwood stream).
FYI, here are things I look for in application generators (in order of
importance) that I often find lacking:
1) The source code for everything that is required to link the
application should be included. Ie: If there is a set of
worker/wrapper functions, or a set of extended controls,
all of the source code should be included.
2) (this is a very hard one) An isolated programmer should be able
to design simple apps without first having a demo performed by
someone familiar with the product.
3) IBM Cset should be supported. This is the OS/2 standard
compiler.
4) the product itself should be compiled with a stable compiler
(IBM/Watcom/Metaware).

You might try calling them -- I know Watcom often gives compilers to
product developers. I noticed you didn't list Borland -- which means you
are probably developing your product with it; IMO, this is the last
compiler you should bother supporting if you want to capture the
commercial/professional software developer. If you are going after the
hobbyist, however, I guess you'll want to support it.
IBM and Watcom are so cheap, if you plan to support them you should
probably just buy them. It's called capital investment :-).

I have IBM Cset++ 2.1 and Watcom 10.0a (both the must current). JdeP has
Metware. I will look at your stuff as long as it doesn't take TOO much
time.
A few hints for multi-compiler support:
- Borland has many C runtime calls that are proprietary, and they
have traditionally used them in most of their samples/docs, thus
creating a programmer who thinks these functions are standard.
Additionally, these non-ansi functions do NOT start with an
underscore, so they are easily missed. Examples are:
clrscr(), readdir(), findfirst().
Some non-ansi, yet defacto standard (msc/ibm/watcom) functions
have been deformed or have different behavior. Example
_beginthread(), the whole c....() library (cprintf(), etc).
- Few of the compilers support the same #pragma's, so avoid
using them.
- Never use inline assembly or pseudo registers.
- Always make your *.ASM files MASM 5.x compatible (yes, you can
write true 32bit flat stuff this way).
- Most of the compilers have a different (and incompatible) default
calling convention. Some don't even support the defacto standard
keywords for the new calling conventions (example: _System).
Therefore, it is best to have all of the functions you wish to
export from a LIB/DLL prototyped with something that overrides
the default calling convention. For example, you could use the
EXPENTRY define.
- #include all non-standard *.h files in one place, so they
can easily be fixed. Examples:
alloc.h
malloc.h
dir.h
direct.h
dos.h
mem.h
memory.h
- If (as you are) releasing source to be compiled by other
people, release a MAKEFILE for each compiler that works with the
MAKE that comes with that compiler.
- Look at GUIDELINES support for each compiler -- pay attention
to the way they allow you to set the LIB/INCLUDE, etc, directories
from within guidelines.
