thanks very much! That solved the COFF issue;
and I was now able to create a patch which solves this so far;
also I found while being on the asm stuff that the Metrowerks Assembler build
is also already broken for 0.9.8; this patch below tries to fix both the
Metrowerks and NASM issue... - well, almost:

with that I'm now able to produce NASM ELF obj for gcc and COFF obj for
CodeWarrior compiler;
but when using the CodeWarrior assembler then there's still one file broken:
mwasmnlm -maxerrors 20 -o crypto/rc4/asm/r4-nw.o crypto/rc4/asm/r4-nw.asm
### mwasmnlm Assembler:
# File: crypto\rc4\asm\r4-nw.asm
# ---------------------------------
# 112: lea esi,BYTE PTR [1+esi]
# Error: ^^^^^^^^^^^^^^^^
# Invalid operand size
### mwasmnlm Driver Error:
# The tool did not produce any output while compiling the file
# 'crypto\rc4\asm\r4-nw.asm'
Errors caused tool to abort.
when I replace the BYTE with DWORD it works, but the crazy thing is that in the
same file there's few lines up exactly the same line with DWORD:
@L002loop1:
add bl,cl
mov edx,DWORD PTR [ebx*4+edi]
mov DWORD PTR [ebx*4+edi],ecx
mov DWORD PTR [eax*4+edi],edx
add edx,ecx
inc al
and edx,255
mov edx,DWORD PTR [edx*4+edi]
xor dl,BYTE PTR [esi]
lea esi,DWORD PTR [1+esi] ; here's correct usage of DWORD
mov ecx,DWORD PTR [eax*4+edi]
cmp esi,DWORD PTR [24+esp]
mov BYTE PTR [esi*1+ebp-1],dl
jb @L002loop1
jmp @L004done
.align 16
@L001RC4_CHAR:
movzx ecx,BYTE PTR [eax*1+edi]
@L005cloop1:
add bl,cl
movzx edx,BYTE PTR [ebx*1+edi]
mov BYTE PTR [ebx*1+edi],cl
mov BYTE PTR [eax*1+edi],dl
add dl,cl
movzx edx,BYTE PTR [edx*1+edi]
add al,1
xor dl,BYTE PTR [esi]
lea esi,BYTE PTR [1+esi] ; here's the line 112 which
uses BYTE with lea
movzx ecx,BYTE PTR [eax*1+edi]
cmp esi,DWORD PTR [24+esp]
mov BYTE PTR [esi*1+ebp-1],dl
jb @L005cloop1
I think that this is also a problem within x86nasm.pl,
however not yet found where to fix -- somebody who has a hint for me?
please let me know if the above patch is acceptable so far.
thanks, Guenter.
