I guess that's the Processor Pack. It's a free download from
Microsoft that contains a free version of MASM 6.xx.

So I guess we are agree on this.

I'm no big coder, but it seemed like it shouldn't be too hard
to adjust the code for MASM 6.xx. See the following quote from
my earlier mail to Miguel. Note: the linker problem should be
fixed in Visual Studio SP 3.

Well, the free version doesn't contain masm.exe, only ml.exe. Looks
like ml supercedes masm. I changed the custom build steps for
strings/strings.asm and strings/strxmov.asm to reflect ml's parameter
syntax, i. e.
masm -Mx -t -DDOS386 -DM_I386 $(InputPath),$(Outdir)\$(InputName).obj,,,
=>
ml -Cx -Zm -nologo -DDOS386 -DM_I386 $(InputPath) $(OutDir)\$(InputName).obj
and got this:

Note the "+" sign appended to strings.obj name. I'm not faimiliar with
VS enough to solve this.
If this is solved, people interested in building MySQL on win32 machines
will be able to benefit from the assembler code without the need to buy
the commercial version of MASM. And that would be a Good Thing(tm), IMO.
BTW, the -Zm option is required for compatibility with MASM 5.x, otherwise
it emits A2032 on these lines (except ecx,P+SIZEPTR*2[ebp] is actually
A2026):
mov edi,P-SIZEPTR[esp] ;p1
