I have two 1.3 programs that communicate through semaphores and shared memory.
These programs run under 2.0 without problems.  I would like to replace one of
these programs by a 2.0 program (compiled with emx) without making any changes
to the other.  I tried putting the calls for creating semaphores and
allocating memory into a DLL compiled under 1.3.  I used this library under
2.0 (by creating an import file for a library similar to libos2.a) but I get a
segmentation fault when I call one of the functions in the library from my 2.0
program.  This is the header for the first function:

ULONG EXPENTRY init_fe ()

Does anybody know how I can use a 1.3 DLL in a 2.0 program or whether there is
another way to use 1.3 semaphores and shared memory in a 2.0 program?

Any help will be appreciated.
