Pericles,
Here is what I set my LDFLAGS in Makefile.vc after pointing to the PHP regex:
LDFLAGS = /NODEFAULTLIB:msvcrt /NODEFAULTLIB:libcd
/NODEFAULTLIB:libcmt /DEBUG
I'm speculating that it is caused by some code being built as debug while
other is "release" code. VC++ is kind of stupid when you try to mix the
two together and says that those symbols have already been defined
