Windows breakage

Stefan, Guys This commit breaks the Windows build (ie my laptop) commit 9fd507e5758f4141ac2619f0db57136bcab035c6 Author: Sergei Trofimovich Date: Fri May 23 23:58:06 2014 +0300 Raise exceptions when blocked in bad FDs (fixes Trac #4934) The breakage is this: C:/code/HEAD/rts/dist/build/libHSrts.a(RtsStartup.o):RtsStartup.c:(.text+0x2aa): undefined reference to `base_GHCziEventziThread_blockedOnBadFD_closure' The reason is, I think that that this line in RtsStartup.c should be inside the guard #ifndef mingw32_HOST_OS getStablePtr((StgPtr)blockedOnBadFD_closure); I'd do that myself but I am not confident that the fix is correct; and I would like to add a comment to explain why the getStablePtr is non-windows-only. Can someone do this, please? Thanks Simon
