[PATCH]Fix implicit declaration of function warning and error while compiling testsuite/newlib.wctype/tiswctype.c

[Renlin Li]

Hi all,

This is a similar patch to this one: 
https://sourceware.org/ml/newlib/2015/msg00004.html
And the description below is also similar.

newlib/testsuite/newlib.wctype/tiswctype.c fails to build in the 
following targets:

aarch64-none-elf
arm-none-eabi
aarch64_be-none-elf

The following messages are produced:
newlib.wctype/tiswctype.c compilation warning: implicit declaration of 
function (isalpha, isalnum, isblank etc.) [-Wimplicit-function-declaration]

Instead, wide character type functions should be called as wctype.h is 
included.

Okay to commit?

Regards,
Renlin Li

type function.
