This is highly dubious.  The reason we needed these things in the past was 
because when compiling via C, Stg.h is always included first, and there was 
no other place to put things like _BSD_SOURCE.  In GHC 6.10 it should never 
be necessary to use _BSD_SOURCE for via-C compilations, only for ordinary 
.c compilations, where it's possible to put the #define in the source file.

But perhaps I've misunderstood the problem.  Can we move _BSD_SOURCE to 
HsBase.h?
