I've seen this in other reports, but it seems to have been marked as `fixed' as
of 3.0.x, and still seems to be broken in 4.1.2.  

Using the Solaris `as', as opposed to `gas', `make bootstrap' fails with

"/var/tmp//cc3fLwsc.s", line 338 : Illegal subtraction - symbols from different
sections: ".L52", ".L61"
make[3]: *** [libgcc/amd64/unwind-dw2.o] Error 1

The offending assembler is

     334         .section        .rodata
     335         .align 4
     336         .align 4
     337 .L61:
     338         .long   .L52-.L61
...
     350         .long   .L60-.L61
     351         .text
     352 .L52:

        * configure.ac (HAVE_AS_IX86_DIFF_SECT_DELTA): New test to determine
        whether the assembler supports taking the difference of symbols in
        different sections.  On x86/Solaris, GAS does but Solaris as doesn't.
        * configure: Regenerate.
        * config.in: Regenerate.
        * config/i386/sol2-10.h (JUMP_TABLES_IN_TEXT_SECTION): Define if
        the assembler doesn't support taking the difference of symbols in
        different sections, i.e. we're using the native solaris assembler.

------- Comment #2 from kjetilho at ifi dot uio dot no  2007-08-13 18:14 -------
It doesn't seem like this patch made it into 4.2.1, at least I can't find any
mention of HAVE_AS_IX86_DIFF_SECT_DELTA in the sources, and the build fails the
same way.  Please reopen bug.  (BTW, would it be possible to download the
patchset mentioned above separately?)

HAVE_AS_IX86_DIFF_SECT_DELTA config/*/*

That is because it was fixed for the trunk and not for the 4.2 branch.
