Is it necessary to upgrade Glib in Cygwin?

I'm attempting to compile abiword in my Cygwin environment. I have cygwin 1.7.25.

The compile fails regarding glib:

A google search produced a Redhat bug report suggesting that Glib 2.31 is required. I'm considering downloading and compiling the latest glib from source as cygwin does not appear to be using it. However, I'd like some insight on this choice or hear if there are some other experiences around this.

Solution

Actually, Glib 2.31 is the culprit; its headers changed so that only the top-level headers may be #included, not the individual class headers.
Cygwin does have the latest stable branch of Glib.
Therefore, in order to get this to compile, you would need to fix the #includes in the code, as indicated in the error messages.
However, I can save you the trouble: Abiword packages are available from Cygwin Ports.
