glib-2.0.m4 cause some error

[KUSANO Takayuki <AE5T-KSN asahi-net or jp>]

With latest glib (CVS HEAD) and pkg-config 0.6 installed,
the configure script of pango produces some errors.
(I know that pkg-configure 0.7 is required, and with pkg-config 0.7, 
these errors will not occur)

These are caused by glib-2.0.m4, and can be fixed by the following
patch.
