Please use the most recent versions. Currently you can get

  gcc: gcc-2.95.2 + gcc-2.95.2-000228.diff.gz
  gdb: gdb-4.18 + gdb-4.18-sh-linux-000110.diff.gz
  libc: glibc-2.1.3 + glibc-2.1.3-000427.diff.gz

from my junkyard. About binutils, the combination

  binutils-000218.tar.bz2 + binutils-000218-000219.diff.gz
  + binutils-more-patch-000305

which can be get from Niibe-san's ftp machine, is recommended.

There is a problem of the visibility of the symbols in libgcc.a
at the bootstrap of ld.so and Niibe-san's gcc-patch for the symbol
visibility

  ftp://ftp.m17n.org/pub/linux-sh/gcc-symbol-vis-000501.diff.gz

solves it. Notice that it may be temporary since there is no
rigid specification of the symbol visibility and its ABI.
Now gcc guys discuss about the shared libgcc library. I think it
will also solve the above problem. Anyway, we should wait a while.
