Reading specs from c:/tools/gnu/rsxntdj/lib/specs
gcc driver version 2.95.2 19991024 (release) executing gcc version 2.8.1

GNU ld version 2.9.5 (with BFD 2.9.5)

I have been playing with a compression code someone else wrote.  At work
I made the code into a dll using VC++, and got it to work from within a
visual basic 6 program.  I would compress a 1.4MB bitmap.  I forget the
output size, but I compressed a 20MB clipper/dbase .DBF to ~2MB

Well I have being dependant upon a MS product, so I've been trying to
get the dll to work with rsxntdj/djgpp.  The code works - and the dll is
actually smaller than the VC version [8.5K vs 20K]

BUT

when I try to compress the same bitmap, I get an out of stack error in
VB.  Smaller files compress okay, but not large!

I've tried setting a _stklen var to 4MB, to no avail.  I tried the
pestack utility to increase the stack, again to no avail.

I know this will never replace wiz/winzip, but it is an interesting
learning process.

Does anyone have any suggestions?

Thanks.
