Not sure I follow what you're trying to accomplish with the above.
Is this cmake 2.7 specific or some trick with the __need_wint_t (which
isn't used in runetype.h)?
For now, i'm just hacking around the issue with:
check_include_file("runetype.h" HAVE_RUNETYPE_H)
IF(APPLE AND HAVE_RUNETYPE_H)
# OS X has wint_t, but check_type_size won't find it
SET(HAVE_WINT_T 1)
ELSE(APPLE AND HAVE_RUNETYPE_H)
check_type_size("wint_t" HAVE_WINT_T)
ENDIF(APPLE AND HAVE_RUNTYPE_H)
Long term, I'm going to write my own version of check_symbol_exists
which uses a different test which is define/typedef agnostic.
