Disable gcc -O2 optimisation
Description of problem:
The GOG linux games don't have a native run command, only a "run with compatibility layer" which then fails to launch the games.
Known issue - see upstream bug linked.
This appears to be caused by having any build optimisation enabled.
Unfortunately '__global_compiler_flags' is hardcoded to -O2 and overrides any CFLAGS set manually to -O0.
This can be overridden by redefining the macro however.
I've run a quick test of the attached patch which ensures no optimisation is applied.
With this patch the games launch correctly.
Yeah, i tested now and can reproduce this. The fun thing that i tested this in earlier builds and it works without this compatibility layer. Thank you for such informative bug report. Will try to test in now without -O2. You also suggesting bump to latest version in your patch, but i am not sure, maybe better staying on this first stable release:
