I think this will produce malformed output on platforms where
pkg-config does output something useful:
-D_GNU_SOURCE -I/usr/include/ncursesw-I/usr/include/ncursesw:

because there's no colon after the ')'.

In fact this code looks kind of dubious in general, because
it seems to assume that the output of pkg_config never has
a ':' in it...
