warning: implicit declaration of function `ftruncate'

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.

Can't repeat this with a newly downloaded mingw, so I'm assuming it was a temporary wibble.
