I'm trying to port a very large program package (100,000s lines of sources
in C and fortran) to compile with gcc.


I've had problems linking gcc compiled files with libraries compiled by
standard sun C and ansi C (SC1.0) . (libF77.a , motif libs, X libs and C lib)
the main problem is that sources that use the shared memory and semaphore
system calls do not run propperly.

the problem was solved by compiling those sources with Sun's acc  compiler
and linking everything with gcc (gcc 1.40  exhibited the same problems as 2.3.3)
but i would rather compile everything with gcc (in order to be able to
benefit from the cross compilers and source compatibility throughout
other 5 different Unix systems on my net)

with the gcc-2.3.3 i tried compiling the package  with and without the
-fcc-struct-return ... but with the same results.
trying to link the programs staticly, sometimes results with /usr/bin/ld
crashing with a segmentation fault, and usually with an unusefull executable
that crashes as it begins running.

I have no clues as to where the problem resides.
if anyone out there has any idea at all, please e-mail me

thanks
