   I found that gdb 6.1 is almost unusable for Sun Solaris SPARC 32/64 bit
   if the target program is compiled using a Sun C compiler. ( gdb/1669:
   "64-bit Solaris does not work" is just one of the problems).

It should be usable for 32-bit.  64-bit has a problem.  The Sun C
compiler generates stabs debugging info by default.  GDB doesn't
handle 64-bit stabs correctly.  Fixing that is non-trivial.  I believe
recent versions of the Sun C compiler can also generate DWARF2.  That
should work better.

   Can someone tell me what the status and planned future of this platform
   is? (gdb/MAINTAINERS calls it "(devolved)")

It's meant to be fully supported.

   I have put in some effort and fixed the most urgent problems so that
   it's usable for me now. My knowledge of gdb source code is quite limited
   however (just 2 weeks old) and some of the fixes definitely will need
   some more work, which I would be willing to do with some help.

   Does it make sense that I send my changes to gdb-patches?

Sure.  If it's a substantial contribution you'd need to assign
copyright to the FSF.
