关于isctype.c判断c是否是字符而产生的报错，如何解决？

报错：

isctype.c说明：

/***
* __chvalidator
*
* Purpose:
*       This function is called by character testing functions in debug
*       versions. This function test for validation of c as character.
*       For improvement in performance, it is not used in non-debug
*       version.  It is available in the static single-thread non-debug
*       build, though, just in case C code that includes ctype.h is compiled
*       /D_DEBUG /ML.
