Original description

WCharacter.h (part of Arduino) contains a bunch of isXXXX() function definitions that are also defined in ctype.h, which it includes. But the Arduino definitions return "boolean", while ctype.h (and apparently the C99 standard) definitions use "int."

This does not seem to create problems now, but there are some indications on other platforms that this will result in errors under future versions of the compiler and/or fussier reporting modes.

If WCharacter.h is going to implement inline versions of the libc functions, it should do so with standards-compatible prototypes...
