Alternatively, use the simpler: .if empty(.CURDIR:N/usr/src*:N/usr/obj*) Alternatively, just remove the statement, and use clang for everything, and help fix bugs in ports. :) > CFLAGS= -O3 -march=native -mtune=native -fno-strict-aliasing -pipe > COPTFLAGS= -O3 -march=native -mtune=native -pipe Take care when using clang and -march=native, there are still some issues with it (search this mailing list for specifics). If anything goes wrong, first revert to the default CFLAGS and COPTFLAGS (e.g. comment them out), and try again.
