this has some problems we've run into.  However, the change to
basesrc/lib/csu/c++/Makefile (which is actually what makes
/usr/lib/c++rt0.o be -fPIC vs pic), _should_ (I think) be ok.

this is way too many.

way too many.

I've simply replaced /usr/lib/c++rt0.o on my 1.4.x sparcs with a -fPIC
version which is available on

That seems to fix everything except for pthreads which I just noted.
