  * Fix --with-compiler / --with-hc inconsistency in ./configure flags
  setup configure takes a --with-compiler option, but used to change 
  that into a --with-hc option when calling ./configure.
  Now that we've added autoconfUserHooks and deprecated defaultUserHooks we
  can fix this without breaking any existing scripts. The autoconfUserHooks
  now passes --with-compiler to ./configure and defaultUserHooks is unchanged.
  Fixes ticket #114.
