I might be able to get you access to an Ultrasparc, but I don't think I have 
the time to help. (My second child was born on Friday.)

I'm not subscribed to the list, so I didn't think about it.

It looks like Lev Assinovsky may have already answered some of this.

First I had to use binutils 2.12.1  (2.13 was badly broken). Then, the 
version of bison on my system was bad, so I used bison-1.35.  I also 
installed a bunch of other packages, but I think those were the only 
necessary ones.  Finally I had to edit a couple libstdc++ files:

gcc-3.2/libstdc++-v3/include/c_std/std_cwctype.h
comment out 'iswblank' lines 58 and 86

gcc-3.2/libstdc++-v3/include/c_std/std_cwchar.h
comment out 'vfwscanf' lines 95 and 157
comment out 'vswscanf' lines 97 and 159
comment out 'vwscanf' lines 99 and 161
comment out 'wcstof' lines 118 and 176


As far as static linking, I'm not sure I can help you.  On Solaris, I have 
had zero luck statically linking libraries, or linking executables to static 
libraries.   The only possible way was to link the object files.  Even if 
you get gcc to find all of the functions in it's own libraries, it complains 
about the Solaris system libraries.



My biggest problem was getting 2-byte wchars.  We ended up using our own 
type for that.


Good luck!
