fix for 980414-1.c testcase

I don't do floating point and I'm not intel assembly geek. I do know
that not all assemblers support the same comment character.
Could someone please verify that this change is correct and doesn't
violate the original test case? It now passes on OpenServer COFF, ELF,
and PIC with the native assembler (it previously hurled on the '#'
characters under COFF) as well still as still passing on Linux/x86.
Thanx,
RJL
