Hello:

	I am trying to get some C code and assembly code to properly link
together.  The C code is compiled using GCC and the assembly code was
compiled using MASM 6.11 using the /coff option to get coff ouput files.  I
was indeed able to link everything okay after some fiddling, but the
program crashes.  I stepped through it using FSDB and found that when the
program reaches the first place in the code where it does a    CALL  func  
  to a function    func   in one of the MASM produced files, it in fact is
not calling   func   as specified in the source code, Instead there is
garbage in the label field in place of the correct label.  Does anyone have
any ideas here as to what may be happening?

	Could the problem be that the coff files produced by DJGPP are slightly
different than those produced by the MASM611?  Microsoft documentation
states that the MASM6.11 coff files are in Windows NT compatible common
object file format.  If in fact they are different, is there anything I can
do about it?  Is there anywhere where I can find more detailed info on the
structure of DJGPP coff files?  Is there a way I can tell GCC to treat a
COFF file differently?

Any ideas greatly appreciated.  Thank you.
