gmchess-0.29.6-r3.patch

gmchess just segfaults when launching.

This patches fixes several issues:

About segfault when launching itself, gtk seems more picky on values returned by event handlers nowadays. Less warning appears at compile time, and runtime seems stable.
Patch needs to be added to the ebuild, nothing more.

This bug description was a bit raw, here are a bit more details to help understanding.

In order being able to compile the in tree version of gmchess this patch is applied via user patches:

I may begin to port this nice chinese chess gui to gtkmm:3 soon.

Great thanks for comulative patch. 
I only replaced "gmchess-0.29.6-r3/src/" paths with "gmchess-0.29.6/src/" but maybe fail to patch was caused by another patch that I initially added to fix compile error that offered patch already contains.

If there is any progress in porting?
