Comment (by wozgonon):

 Inserting the following at ./configure:6143 suppresses the error and
 allows ./configure to complete

 {{{
 unset ac_cv_prog_cc_c99

 }}}

 'make' then fails due to 2 spaces in a path name being replaced with
 newlines:

 {{{
 make
 mk/config.mk:805: *** missing separator.  Stop.

 }}}

 {{{
 HSCOLOUR_CMD   = C:/Program
 Files/Haskell
 Platform/8.0.1/lib/extralibs/bin/HsColour

 }}}

 In ~/haskell/ghc/mk/config.mk change the above to

 {{{

 HSCOLOUR_CMD   = C:/Program Files/Haskell
 Platform/8.0.1/lib/extralibs/bin/HsColour
 }}}
