? For the OSX _binary_, the compiler better be known in advance --
unless Simon et al are using some sort of quantum compiler ;-)

It is called Makeconf, afterall, so editing it seems sensible to me.
Changing PKG_* vars is inconvenient if you work on many packages, want
to see warnings in other people's packages, and work on many projects
at once since the probability of forgetting to fix it for a release is
non-zero.
