Thanks for investigating.  The patch did not apply for me on
core-updates, so I had to do the gnu/local.mk change "manually".

Maybe we should rename this patch to more accurately reflect what's
going on?  Something like "gtk+2-abi-check-ignore-glib.patch".  WDYT?

Regardless I've pushed this as 92b61d3e1bb50f0c1d087bc8d57cc00c3ce360df.
