This really is the reason (or at least one reason;-) for the I/O
problem:  When `gpc.exe' invokes itself, the new instance chooses
the same `temp_filename' "ccaaaaaa" as the primary instance did.

Strange enough, the patched `libc.a' did not change this behaviour.
What I did was to link `gpc.exe' against this new `libc.a'.  I will
double-check that my current `libc.a' really contains a new
`mktemp()' ...

In fact the temporary name is chosen in `choose-temp.c' from 
"libiberty" which is copied in the GCC source.

I will keep you informed and summarize on `djgpp AT delorie DOT com'.

Thanks again,

    Peter
