I have been trying out GCC 2.3.3 under both DJGPP and EMX.  I got the
EMX one first the other day when I found out about emx version 0.8f.
Then I picked up the recent ports which I run with DGPP version 1.09.
Prior to that I was using DJGPP 1.09 with GCC 2.2.2.

I have a program which will compile with GCC 2.3.3 under DJGPP but
fails with the same compiler version under EMX.  The actual failure
is in the ASSEMBLER stage, where the source of the assembler has been
corrupted by two zero bytes overwriting part of one line of
assembler source, I do not know why.  The problem is reproducible.  If
I create the *.S file using -S option and then assemble that, it works
O.K.  I have compared the *.S files generated by the two versions of
GCC 2.3.3 and there are some detail differences.  The source file I
used is CP-DEM.C, which is a demangling tool for GCC compilers which
someone posted to me a while back.  If there is interest I can post
it.  I have not reported it to GNU as it doesn't look like a bug in
their compiler.

I will cross post this to both DJGPP and EMX lists.
