I downloaded the whole MGL lib, and after fixing few makefiles was able
to
compile.

It compiled well for me with slightly changed native makefiles and djgpp
v2.02
(gcc 2.8.1) except that include/mgl/mglver.h file was missed from the
package
for some reason. However it seems that it doesn't conatain any vital
information,
so it compiled. But was failed to work ;)
The problem seems to be in pmode lib, which uses (seems to) incompatible
with djgpp
usage of DPMI host. It doesn't use native djgpp DPMI funcs except one -
enable near ptr - which itself can cause problems ... Instead, it issues
direct
0x33 interrupts and seems to be inaccurate.

I'm working extensively on djgpp port of MGL (i use it as a test project
for DLMs
http://www.iis.nsk.su/orangy/dlm/) and plan to contact SciTech Soft
to work in coord. If you wish to help, email me. There also will
separate
hell with porting MGL to support not only dos host, but also windows
host
under djgpp with RSXNTDJ, but this is plans for far future.
