Thanks for your perl patch for this problem.  I have checked it into
CVS, but guarded in the configure script so that it is only enabled
if gcc-3.3 is present.
Here's a better one (accepts global as well as globl, uses STT_OBJECT
instead of @object (@ starts a comment on arm), uses the align of the
original rather than assuming 4 is right) that I believe works on at
least x86, mips(el) and arm. I haven't tried it on anything else.

perl -e 'undef $/; $_ = <>;
         s/^
           \s*\.local\s+startLabel\n
           \s*.comm\s+startLabel,0,4\n
           (\s*\.globa?l\s+[^\n]+)\n
           \s*\.data\n
           (\s*\.align\s*\d+)\n
          /"\t.data\n"
          ."$2\n"
          ."\t.type startLabel,STT_OBJECT\n"
          ."\t.size startLabel,0\n"
          ."startLabel:\n"
          ."$1\n"
          ."$2\n"/emx;
         print;' |

-fno-common seemed to have no effect and the meaning of .align does
indeed vary depending on what platform you are using GNU as on.

If you're already GNU tools only and you did want to replace all aligns
with 4-byte alignment then you could use .balign 4 (or .p2align 2)
though.

Thanks
