darcs patch: Unbreak the GHC build with older versions of gcc

Thu Aug 28 16:27:43 CEST 2008 kili@outback.escape.de * Unbreak the GHC build with older versions of gcc Stg.h must be included before HsBase.h, because the latter contains function definitions causing older versions of gcc (3.3.5 in my case) to bail out with "error: global register variable follows a function definition" on Regs.h, which is included by Stg.h.
