I tracked this one down and realized the problem is that include paths
(i.e. /usr/include) aren't passed correctly to swiftc in  the tests. I
worked around
this passing -I/usr/include but I'd like to fix this right for
FreeBSD. Where's the correct place where CXXFLAGS and LDFLAGS should
be passed?


Thanks,
