Noob qestion on libglib-2.0-0.dll

Hi all, noobie here and having problems getting my new dev environment
working.  I downloaded every prebuilt package I needed for win32 (I
hope), and ran a test compile.  (Using MingGW Gcc, test was the basic
"hello world" program for the gtk tutorial.)  While trying to execute
pkg-config, I got the following error:

"The dynamic link library libglib-2.0-0.dll could not be found in the
specified path:"

etc., then it dumps my path. I have actually two questions:

1. I have a lot of *.dll.a file, but few *.dll files. Did I perhaps
grab a wrong prebuilt someplace?  The *.dll.a files are: 

libgdk.dll.a       libgmodule-2.0.dll.a  libgthread-2.0.dll.a
libglib-2.0.dll.a  libgobject-2.0.dll.a  libgtk.dll.a

I copied each of the files above to a file name with out the ".a" at
the end, but if you look closely none of the files above will match
the dll indicated by the error message.

2. Assuming the above is Oll Korrect, where the heck is this dll with
the extra "-0" in it?  Did I download an incorrect version of some
package, or should I just copy the above files to new names again?


Thanks for any advice you can give,
B.
