I had a look at that perl script genmdesc.pl and what win32 genmdesc.exe does,
and I can pursuade the perl script to behave like the C program by adding just  
' -DMONO_ARCH_SUPPORT_SIMD_INTRINSICS ' to where the perl script invoke the C
preprocessor:

     #print "Running: $cpp\n";
     open (OPS, $cpp) || die "Cannot execute cpp: $!";
     while (<OPS>) {
====================================================
I don't know what's the impact of this change is, but it seems to make the perl
script behaves like the C program (other than white spaces and trivial "1" ->
"\x31" style char to equivalent hex escapes).

Please consider making the the perl script agree with the C program :-).
