The source paths for these copies are derived from the path of the  
gcc binary ($GccDir).  Did you call configure with '--with-gcc=C:/ 
Mingw/bin/gcc.exe'?  I received those errors when I forgot to do that.

I think that 'gettimeofday' is statically linked into the ghc  
executable, so it's just that GHCi doesn't know about it.  Adding a:

   Sym(gettimeofday) \

line to the RTS_MINGW_ONLY_SYMBOLS #define in rts/Linker.c (from line  
265) seemed to fix the problem for me.

I'm not sure if this is a GHCi bug or something else being awry.   
'gettimeofday' was added to the mingwex library in mingw- 
runtime-3.10, which was released in July last year, so I would have  
expected this problem to have come up before now...

Andrew.
