Ensure that HAVE_GETTIMEOFDAY is defined in mk/config.h.

Also, I discovered that changes to Linker.c don't make it into  
ghc.exe if you just do a 'make' in the base directory.  You need to  
make the RTS, then link ghc with the new RTS.  The following commands  
work for me (more typing, but a lot faster than making clean):

   make -C rts
   rm compiler/stage2/ghc.exe
   make -C compiler stage=2
   make install

Hope that helps.
