This sounds allot like this bug to me:

<https://bugzilla.redhat.com/show_bug.cgi?id=428865>

Since Cygwin's glib2 is only at 2.10.3, you'll either need to wait for
an update of this package or build a newer one yourself.

Also, the repeating of "-lm" above could be troublesome.  If you have
problems related to this, try removing one.  I'd recommend the first
occurrence.
