ok, here an excerpt:

all 10 tests fail because of this. iostream.h is in:
/home/st38/src/egcs-1.0.3a/libio/iostream.h
/usr/include/g++/iostream.h

g++ tests are (at least partly) caused by not finding iostream.h as
well... It seems to be all libio / libio header files problems.

Ideas to work around this or mistakes I did in the building process?
I could try other binutils / dejagnu as well, if there is any point in 
doing so... Feel free to require any info you need!
