Yes, that works much better, thank you.  There is still a problem with 
the generated Makefile, but it is not an MSYS problem.  The pkg-config 
code in 'main.c' correctly uses the platform dependent search path 
separator from the installed 'glib-2.0/glib/gutils.h', but the Makefile 
assumes the Un*x format when defining variable $(pc_path).  Of course, 
this needs to be addressed in the pkg-config distribution, but the 
work-around for MSYS is to change the path separator in "pc_path = 
${exec_prefix}/lib/pkgconfig:${prefix}/share/pkgconfig" to ';' prior to 
doing the make.  The patch to parse.c for MSYS 
(http://sourceforge.net/mailarchive/message.php?msg_id=17998466) is 
still required by pkg-config-0.21.
