Recent versions of binutils added support for lcomm alignment, this needs a
patch in gcc that is not integrated, perhaps I've discovered that global symbols
alignment is not covered at all (comm has only size on win32)
16-byte alignment is mandatory for sse ops
I've looked in binutils code but it's not easy to understand what to change
If I've understood on elf, a "comment" is added that says size and alignment
this can be easily added also for win32 but who and when use this info?
