Hello all,

while preparing a set of Makefiles for Sam Leffler's TIFF library I noticed
a difference in the available virtual memory in v2 compared to v1.

One of the source files in the library contains very large arrays which made
gcc run out of memory in my environment (Win95 with 8MB), well Win95 has
a crummy DPMI and odd memory managment anyway, I thought, so I switched to the
DOS mode and compiled the one file with cwsdpmi, which makes enough virtual
memory available so that the file compiled.
However, when comparing the memory values with go32-v2 with the ones reported
with go32 from v1, it seems that the Win95 DPMI has more virtual memory
available, but it is not available to djgppv2 programs.

I have no idea what has changed in the DPMI handling of v2, but it seems
like something was broken.


bye, Alexander
