>Description:
CLIX is an old SVR3.2 clone, with the old 14-character filename limit on its native filing system. The problem does not affect NFS, giving one workaround.

The two files unwind-dw2-fde.c and unwind-dw2-fde.h, have been added to the compiler since 2.95.3, and now cause the bootstrap to fail (as one overwrites the other after extraction from the tarfile, and dependencies and #include's no longer function as desired).

There may be other files that don't affect my specific host and target that could cause this problem.
>How-To-Repeat:
Try and build any flavour of GCC on any platform with a 14-character filename length.
>Fix:
Would like names of these (and any other or future) files shortened to fit within the 14-character limit of older Unixen. It seems short-sighted to prevent this build because of this problem - 14 characters is not *too* onerous a problem IMHO.
