I definitely agree, it's more a case of the time to having a first 
version working.

Thanks. Okay, going with the clean approach:

The differences I have from you are that I'm building for Solaris 2.9 
and using full gcc (for C++) support. Since I was building from Solaris 
2.11 (Nexenta A7) I initially tried to skip the library/header copy 
stuff and mess around with the tree. This just led to trouble (PATH_MAX 
stuff: not fixed by the patch in crosstools), so I've gone with pretty 
much exactly as you wrote.

I had to add --disable-nls as in crosstools as I was getting libintl 
symbol problems. Then binutils built cleanly, but gcc does not. I have 
to leave for the day now, but wondering if the cause of this libc.so 
link problem is immediately obvious to anyone? Could it be the issue 
referred to by

http://gcc.gnu.org/install/specific.html#x-x-solaris2

where it says:

"We recommend using GNU binutils 2.16 or later in conjunction with GCC 
4.x, or the vendor tools (Sun as, Sun ld). However, for Solaris 10 and 
above, an additional patch is required in order for the GNU linker to be 
able to cope with a new flavour of shared libraries. You can obtain a 
working version by checking out the binutils-2_16-branch from the CVS 
repository or applying the patch 
http://sourceware.org/ml/binutils-cvs/2005-07/msg00122.html to the release."
