 Your 'libgcc.a's for sh3e and sh4 should provide this
routine. It has been a part of the GCC-helper library
for SH for some time.

 Please tell your GCC-version. Upgrading it gives the
necessary routine in the libgcc.a's or you can try to
upgrade only the 'gcc/config/sh/lib1funcs.asm' which
has the routine in newer incarnations. Also the 't-sh'
there must be fixed by adding the routine name.

 For instance the egcs-1.1.2 (2.91.66 from 990314) didn't
have it, while the ecos-1.2.1 GCC-sources (gcc-2.9-990319)
had it and the 'crt0.S' for SH3e in newlib-1.8.1/1.8.2
needed it...

 If your host is Win32 or Solaris, Hitachi provides quite
new (Oct - Nov 2000) prebuilt SH-tools via its:

 http://semiconductor.hitachi.com/repository/tools/Gnutool.html

so you can perhaps avoid the recompiling... BTW, the 'sh-elf'
tools can still produce COFF ('hms') with '-oformat', if that
is an issue...

Cheers, Kai
