Adding a conditional declaration for XMMWORD allows either MASM 6, MASM 7, or
MASM 8 to assemble
OpenSSL 0.9.8g correctly, including the SSE2 instructions in sha512-sse2.asm:
IF @Version LT 800
XMMWORD STRUCT 16
DQ 2 dup (?)
XMMWORD ENDS
ENDIF
x86ms.pl could do this:

Note that MASM 6 still must be version 6.15+ to assemble the SSE2 instructions,
but VC6 users can
upgrade with the "Visual C++ 6.0 Processor Pack" at
http://msdn2.microsoft.com/en-us/vstudio/aa718349.aspx if necessary.
