Reported by Conal Elliot.  ''might'' be caused by a new mingw version, we
 haven't looked into it yet.

 With ghc-6.5.20060106-i386-unknown-mingw32.tar.gz, I'm getting the
 following warnings when I compile with -O:

 {{{
   [ 3 of 40] Compiling Pajama.TreeToGraph ( Pajama/TreeToGraph.hs,
 Pajama/TreeToGraph.o )
   In file included from c:/tmp/ghc200508_0.hc:4:
   c:/ghc/ghc-6.5/include/HsBase.h: In function `__hscore_ftruncate':
   c:/ghc/ghc-6.5/include/HsBase.h:402: warning: implicit declaration of
 function `ftruncate'
 }}}

 and so on for every module.  Same messages from 20060103.
