I have had problems compiling gdm recently because i used a separated CFLAG for some work, I called this variable COMMON_CFLAGS, when looking through the gdm build logs i noticed the -I parameters were missing, instead there were double CFLAGS in the build parameters.

Unsetting COMMON_CFLAGS fixed the issue.

I think its something to be aware since COMMON_CFLAGS should not be defining include parameters, basically a bad paradigm.

Maybe this can be unset in the ebuild or there should be created a patch to fix this?

you should use the variable locally for your project.
