Thank, but it was a typo in my 1st email. The correct command was
with a redirect:
   set ASM=nasm
   f:\util\StrawberryPerl\perl\bin\perl crypto\aes\asm\aesni-x86_64.pl auto > tmp-file.s

Still the "auto" forces GNU-asm syntax with 'ASM=nasm'.
I can only conclude the '$ASM' does nothing and only helps obfuscate
things further. This works fine:
   set ASM=
   f:\util\StrawberryPerl\perl\bin\perl crypto\aes\asm\aesni-x86_64.pl nasm > tmp-file.s
