AX_WINT_T
It turns out that MacOS X doesn't guarantee to provide the "wint_t" type unless you include the strange header <runetype.h> in addition to <wchar.h>. Consequently, the "do I have a system wint_t?" probe fails and an alternate gets used. Unfortunately, by the time the program gets built, one way or another that funny header winds up getting included and the "#define wint_t unsigned int" patch-up-hack mutilates the typedef. This macro will get it right.
