Many thanks for your response.

After trimming the contents of qgscoordinatereferencesystem_legacy.h
(about 10 lines left), it builds in a normal time again.

So it is likely, that the problem on FreeBSD has something to do with
its compiler suite? I am using FreeBSD clang version 8.0.1
(branches/release_80 363030) (based on LLVM 8.0.1).

Is there any workaround, which lets me use the whole contents again?
