[PORT] BeOS port problem and suggestion

Internally bfd already uses a bfd_seek function.  There should be no
(significant) places inside the BFD code where seek or fseek is used
instead of bfd_seek.

It is not really BFD's job to provide a replacement for seek/fseek in
a more general context.  In fact this ought to be something that BeOS
provides as some kind of compatibility library.

There has already been a patch submission to address this problem.
Please have a look at this:

  http://sources.redhat.com/ml/binutils/2000-08/msg00437.html

Note - this patch was rejected, for very good reasons (an fseek past
the end of the file would fill it with zeroes, even if there were no
writes past the end of the file).  Unless you can convince us that
whatever patch you develop does not suffer from this problem it will
be rejected again.

bfd is not common to gcc.  It is used by GDB, and its behavior is
influenced by GCC, but it is certainly not tied to it.  Anyway the
answer to your question is that you should submit any patch developed
to:

        binutils@sources.redhat.com

BFD is not in the 2.95.3 tree or the 3.x tree.  It is in the binutils
releases.  The binutils release usually associated with gcc 2.95.3 is
2.11.  And no, any patch you develop will not be back ported into the
2.11 binutils release.

Cheers
