When I tried mainline bootstrap on sparc-sun-solaris2.11 as of 20080903
(rev 139939), I get a configure failure in stage2 libgcc:

checking for suffix of object files... configure: error: in `/vol/gccsrc/obj/gcc-4.4.0-20080903/11-gcc/sparc-sun-solaris2.11/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.

and config.log reveals:

Running cc1 -O2 conftest.i gives

Looks like a code generation bug to me.  I'll try to start a reghunt asap.

Btw., i386-pc-solaris2.10 is also broken for me, this time while
configuring stage3 libgcc ;-(  Same is true for alpha-dec-osf5.1b and
mips-sgi-irix6.5, so all four of my platforms got broken during the last
for weeks while I was on vacation.
