On Cygwin environment, wint_t is unsigned int as shown here:
```
$ echo | gcc -m32 -xc - -E -dM | grep WINT_T
145:#define __SIZEOF_WINT_T__ 4
315:#define __WINT_TYPE__ unsigned int
```
```
$ echo | gcc -xc - -E -dM | grep WINT_T
147:#define __SIZEOF_WINT_T__ 4
317:#define __WINT_TYPE__ unsigned int
```
```
$ LANG=C gcc -v
Using built-in specs.

Subject: [PATCH] [Cygwin] wint_t is unsigned int
Cygwin 32bit:
$ echo | gcc -m32 -xc - -E -dM | grep WINT_T
145:#define __SIZEOF_WINT_T__ 4
315:#define __WINT_TYPE__ unsigned int
Cygwin 64bit:
$ echo | gcc -xc - -E -dM | grep WINT_T
147:#define __SIZEOF_WINT_T__ 4
317:#define __WINT_TYPE__ unsigned int
