  Priority:  normal         |    Milestone:        
 Component:  Cabal library  |      Version:  HEAD  
  Severity:  normal         |     Keywords:        
Difficulty:  normal         |   Ghcversion:  6.10.1
  Platform:                 |  
----------------------------+-----------------------------------------------
 When trying to configure with an inplace GHC on Windows, Cabal dies with
 an irrefutable pattern match error.  The offending line is:
 {{{
     Just gccProg = lookupProgram  gccProgram (withPrograms lbi)
 }}}
 in {{{D.S.PreProcess.ppHsc2hs}}}.

 The problem was that configure didn't find gcc in its expected place
 ({{{ghcBase </> "gcc.exe"}}}) and Cabal didn't check that it did before
 running the preprocessor.
