Ok, thanks a lot, it's linux, that's what I wanted to know (Running linux on
PowerMac isn't  obvious, at least for me)

Then you probably suffer from the same problems as I do
(i686/linux-2.2.1/glibc2.0pre7+bugfixes).

The cause for this problem is "rmdir" behaving different on linux versions
2.1.X/2.2.X than egcs/gcc/fixincludes requires.

You can easily check if you are affected by the problem:

mkdir <somedir>
cd <somedir>
rmdir .

Under linux-2.1.X/2.2X the rmdir command above succeeds, under other OSes this
gives an error.

This causes fixincludes not to work properly for cross-building egcs, because
fixincludes requires "rmdir ."to fail to work properly.

This explains why my patch failed to work (bash 1.14.X is pretty old), OTOH it
revealed a portabilty bug in the patch (;-).

Ralf.

PS.: Joel, below is a corrected version of the egcs-fixincludes-patch. Though
it's a one-liner, you should consider this to be reason enough to release a new
version of RTEMS-4.0.0 egcs-patches (linux-2.2.X is officially out and more and
more people will probably be affected by this bug).
