When looking at the up-to-date gcc-3.3 sources, the 3.3.5 bugfix ones, this bug
still was there as unfixed ! The attached 'coff.h.diff' patch should fix it, I
had it in my own fixed gcc-3.3 branch sources installed in 2003...

Another patch which defines a default target board for 'm68k-coff', the 'BCC'
board, has also been attached.
