This sounds suspiciously like the rmdir(1) behavior problem that Ralf has
run into.  It has something about rmdir of a directory with a . in it.  I
thought this was dealt with in the rtems patch.

The rtems or egcs list archives should have this in them.  The discussion
with the Linux folks I have is dated around February 15.  Here is a
fragment of a description from Ralf along with a short test.  I recall he
had a shorter test in some email messages.

I recall that the symptom was missing directories in the install
point.  Does it look like you are missing some directories?

[FYI Ralf would normally have answered this but is still in the States and
off email.]

========================================

The cause of this problem is the fragment from gcc/fixincludes below:

This fragment relies on rmdir(1) failing when $file contains "."- So the
actual problem is gcc/fixincludes requiring "rmdir $LIB/." to fail (Of
cause this can easily be worked around by modifying fixincludes, but is a
different topic).

AFAIS, this fragment is present in all gcc-releases I have handy right
now: gcc-1.42 (Sep. 91), gcc-2.3.1 (Oct. 92), gcc-2.7.2.3, egcs-1.1b,
egcs-1.1.1 and egcs updated from cvs a few hours ago.
