The 64bit integer support in VC++ 6.x is very weak, underdocumented (like there 
is apparently no way to clue the compiler into a UL constant), and generally a 
pain (I was vainly trying to port Dan Berstein's libtai to Win32).  Apparently 
the .NET compiler has better 64bit support; you may need to upgrade before you 
can proceed.  I also doubt that compiling ActivePerl has been even attempted 
using 64bit ints so there may be additional patches required to get it to work.

Did you try using this instead of M$loth's compiler:

which doesn't require the Cygwin runtime DLL's.
