  I am working on adding debugging instructions to
FPK pascal.
  FPK pascal is a free 32 bit pascal compiler.
It creates an assembler file and then
uses gnu as and gnu ld to make executables.

I added stabs information into the assembly code,
and wanted to use it with the GBD debugger.

  Here comes the problem :

 - when compiling to a.out-i386 BFD format, I
can check with objdump --syms that I have all my symbols
in the a.out file.

  But trying to load this file 
with the GBD debugger v4.12 with GO32 v1.12m3
GDB claims that a.out is not an executable format
and doesn't know how to load it.
Is that a bug of GBD v4.12 ?

 - I then tried using the coff-go32 output format
and that works :
  GDB can load this file and 
  "info variables"  and "info functions" work.
  But now I have lost all types information
as well as all sources files and line numbers !!!!
Changing formats using objcopy gives the same result !
This is because these informations are not present
in the coff-go32 format.

  Does anybody know howto keep these informations.

  When executing "objdump --stabs " to the coff-go32

I obtain a line telling
No $GDB_SYMBOLS$ section present.
How can I force this ?
