ada use flags is masked for sys-devel/gcc. isn't it ?
equery h ada tells me that the packages on my system with the ada useflag are ncurses and gcc
Somehow it's not masked: $ USE=ada emerge -pv1 sys-devel/gcc These are the packages that would be merged, in order: Calculating dependencies... done!

Or does 'arch/amd64/use.mask:-ada' have an overriding effect on 'base/package.use.mask:sys-devel/gcc ada'?
Why not force mask it?
(In reply to Sergei Trofimovich from comment #6) I believe portage is working as intended here. It applies use.mask and package.use.mask for each parent profile. arch/amd64 is processed after base. You'll need to add it to arch/amd64/pacakge.use.mask as well.

Yeah, glancing at algorithm https://dev.gentoo.org/~ulm/pms/head/pms.html#x1-54002r1 use.mask and package.use.mask are really one namespace in each profile.
ada USE flags is now correctly masked. Thanks!
