Stop.
bmake: stopped in /usr/pkgsrc/devel/glib2

>How-To-Repeat:
bootstrap pkgsrc on MacOS X 10.[12].x
cd .../pkgsrc/devel/glib2
bmake


>Fix:
Although MacOS X 10.[12].x have <wchar.h>, the functions prototyped
therein are not present in any library installed on the system.

Workaround:  build without wchar support

bmake configure

then patch as follows:

It is important to explicitly undefine HAVE_WCHAR_T.  Otherwise,
.../work/glib-2.6.1/glib/gnulib/vasnprintf.c seems not to obey its

# ifdef HAVE_WCHAR_T

directives.
