I just built perl-5.10-RC2 with MSVC++ Express 2005 and dmake. All went almost smoothly. I had to manually copy all the lib/ and include/ files from the Platform SDK onto the MSVC lib/ and include/ folders. Doing this, there's no need to modify the Makefile.mk If I was supposed to modify the Makefile.mk in some way, then it's not obvious for me how to do that. I tried fiddling with CCLIBDIR and CCINCDIR but I had also to change some other occurrence or compile/link commands, so I thought the best way was just to stick every lib & include in the MSVC paths.
