minor bug: --enable-stdcall-fixup

[Reinhold May]

Dear Sirs,

I use GCC version 2.95.2 in conjunction with GNU ld 2.10.91.

I had to use the linker option "--enable-stdcall-fixup" for supressing
some warnings on using a win32-dll via MinGW.
It didn't work and didn't output "unknown parameter" errors, but when I
tried "-enable-stdcall-fixup" (with one '-') those warnings were
supressed.
I didn't watch the source code but I suppose the interpretation for this
parameter should be corrected.

Greetings and keep on the good work.
Reinhold May
