Thanks, I've added this to the building guide and added a test to the
build system to detect 3.79 and complain.

This one looks like a bad interaction between your gcc version and the
mangler.  Probably not worth investigating in detail, since you already
worked around it by installing an updated gcc.

Not yet, there's a page in the building guide:

http://www.haskell.org/ghc/docs/latest/html/building/sec-pre-supposed.html

It would probably be a good idea to move all this material into the Wiki
at some point.
