ghc HEAD and tee

[Christian Maeder]

Hi,

we used redirect output of ghc via "tee" (within a Makefile). With the 
new ghc this randomly fails now. Does anyone have an explanation for this?

  ghc <<omitted args>> 2>&1 | tee log

yields:

  Skipping  Main             ( hets.hs, hets.o )
  Linking ...
  tee: write error


The linked binary and the log file are ok afterwards (and the mere size 
of the log is also no problem).

Cheers Christian
