I DID read your post

But you didnt say anywhere in your post that this was a problem you just added it silently ;-)

# Essentially we pass all the same -D defines that perl was built with
+ plus
# the include dir to find the perl headers and the perl56.lib binary w
+hich is 
# what where the real functions defined in the headers are found and w
+hat we 
# will be linking against........

And this is what I did. There is no -DWIN32 in: perl -MExtUtils::Embed -e ccopts -e ldopts Which is what everyone was saying Nalina use. I personally dont think that it is possible for everyone to use cl.exe

ps Please stop down voting me now. I was only trying to help. There was no malice.
