[PD-dev] Compiling debug mode for GDB on MSYS2 MINGW64

[Pierre Mallard]

Hello Chris and everyone,

Thanks for the trick, it could be nice to complete the wiki on
http://puredata.info/docs/developer/BuildingPd with at least your approach
(mine would require to patch msw/Makefile.am)
Let me know if it is worth it, I don't have an account there.

Bye
