[Bug bootstrap/39025] New: ICE in start_function, at c-decl.c:6225 while configuring libgcc

[ro at gcc dot gnu dot org]

The configure step of libgcc aborts with

checking for suffix of object files... configure: error: in
`/vol/gccsrc/obj/gcc-lto-20090127/11-gcc/sparc-sun-solaris2.11/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.

config.log reveals

Running cc1 on this conftest.c gives

The same problem happens on i386-pc-solaris2.10.
