  No, it doesn't.  Really!  I think you must have a misunderstanding about
what a .bss section /is/ if you think it contains anything that needs

  Did you try combining -fno-common with -fno-zero-initialized-in-bss as well?
That /ought/ to result in no .bss section at all in the final output files.
(It may be that the toolchain generates a file with a zero-sized bss section;
you can verify that with the binutils 'size' command and you could use
objcopy's --remove-section option to excise it in that case).

Can't think of a witty .sigline today....
