That was the subject of my original post, actually. I don't think DJGPP 
can embed enough debugging info in the binary, so you can't debug across 
multiple source files. I use the exact same gcc under Solaris (ELF), and 
both AOUT and ELF Linux machines, and they *can* debug across multiple 
source files.

Try doing that with DJGPP. Someone suggested that what we have is an old 
GDB (it is), but someone else said that the old versions of DJGPP (which 
produced a.out files by default) could do it. I can't try this out 'cause 
my old DJGPP is gone and I didn't know to use GDB then  ;)

However: it says in the gcc documentation that you can build the compiler 
to attach stabs debugging info in the COFF binary. If I rebuild the 
compiler with this option, will I then be able to debug multiple source 
files?
