I'm getting this error when trying to compile current GHC-HEAD on windows:

rts/Linker.c:1039 basicly is just:
with the definition somewhere below line 381:
/* These are statically linked from the mingw libraries into the ghc executable, so we have to employ this hack. */ #define RTS_MINGW_ONLY_SYMBOLS \ ... SymI_NeedsProto(mktime) \ ... SymI_NeedsProto(localtime) \ SymI_NeedsProto(gmtime) \ ...
I tried all different versions of MinGW - the one of the current Haskell Platform 2010.2.0.0 and the one currently available at mingw.org and an old version I had installed.
However, removing these 3 lines will result in another error, so the changes to fix this won't be that trivial:
rts\sm\GC.c: In function 'new_gc_thread': rts\sm\GC.c:863:11: error: incompatible types when assigning to type 'OSThreadId' from type 'int' make: *** [rts/dist/build/sm/GC.thr_o] Error 1 make: *** [all] Error 2
(even though I'm not 100% if that's because of those changes, since I probably never got that far in the building process...)
