Dejagnu is so scrwed up

[hjl at lucon dot org (H.J. Lu)]

Hi,

I am trying to figure out why dejagnu cannot find libstc++ during
"make check" in egcs. It turned out libgloss.exp is too screwed up
to really do anything useful.

My egcs build directory is is /usr/src/gcc/egcs-1.0 and I
configured/installed egcs as i586-unknown-linux. So egcs installed
something under /usr/i586-unknown-linux. Now the "lookfor_file" proc
in libgloss.exp will return /usr/i586-unknown-linux for

set multitop [lookfor_file "/usr/src/gcc/egcs-1.0" "i586-unknown-linux"]

It is because lookfor_file searches ".. ../.. ../../.. ../../../..".
>From then on, almost everything is screwed up.

I believe that also causes failures for other people. Is there a fix
for it? I will try to write one if there is none.

Thanks.
