Did you ever check this in?  In the meantime, on cygwin, where <wctype.h> works 
out of the box, configure still reports:

checking absolute name of <wctype.h>... ///usr/include/wctype.h
checking whether wctype macros need _ctmp_ declared... no, but bare wctype.h 
does not work

That looks fishy to me; I wonder if there is some broken logic in wctype.m4.
