[llvm-dev] Building a program with LLVM on Unix

[Russell Wallace via llvm-dev]

Thanks!

Bearing in mind that I don't know m4, looking at the code, it seems to work
by allowing an override to specify where to find llvm-config (which is the
right thing to do, of course) but by default looking in the current path.

Based on both my own limited experience in the matter and what David Jones
and David Chisnall are saying, one could argue that the path version
probably will _not_ be the correct one. That the correct default is
actually more likely to be e.g. ~/llvm-3.8. Does that make sense?
