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.

hunk ./cbits/PrelIOUtils.c 8 -#include "HsBase.h" hunk ./cbits/PrelIOUtils.c 9 +#include "HsBase.h"
This breaks the build for me: Building ghc-bin-6.9...

It turned out that something in Stg.h, perhaps _ISOC99_SOURCE, meant S_ISSOCK wasn't being defined. I defined _BSD_SOURCE too, and now it's happy, so I've applied your patch (well, actually a new patch that does the same thing, because yours now conflicts with more recent changes). Thanks Ian
