Fix wcwidth() compile error with MSYS2

Browse Source 
We try to detect when compiling under Cygwin, so we can set the
_XOPEN_SOURCE define which lets us use wcwidth(). We look for the
string "CYGWIN" in the uname, which looks like:

    CYGWIN_NT-10.0

MSYS2 is also based on Cygwin, so all of the above should still work.
However, we detect Cygwin by looking for the string "CYGWIN" in the
uname. In MSYS2, the uname looks like:

    MSYS_NT-10.0-18362

This patch looks for the string "_NT" instead of the string "CYGWIN"
in the uname, since it's common to both environments. This fixes a
compilation error on MSYS2.
