I am testing the enclosed patch.  I will check it in if it passes bootstrap
with and without --enable-checking=assert

In general, there is no need to surround DBGPRINTF with ENABLE_CHECKING.

 DBGPRINTF ("inpf %p inpname %s outname %s forname %s",
            (void*) inpf, get_input_file_name (inpf), *poutname, *pforname);

ENABLE_CHECKING should be dropped.

inpname should be inlined into DBGPRINTF and ENABLE_CHECKING dropped.

A patch to make these changes is pre-approved. Basile, can you take
care of this?

Thanks,
