#4031: Build broken with cygwin make 3.81

---------------------------------+------------------------------------------
Cygwin make 3.81 (the latest version) doesn't support Windows paths, but
the GHC build process generates makefiles containing such paths. This is a
deliberate change by Cygwin - see
http://www.cygwin.com/ml/cygwin/2006-07/msg00668.html for the "rationale".
The upshot is that you get this error when compiling:
{{{
utils/genprimopcode/dist/build/.depend.haskell:3: *** target pattern
contains no '%'. Stop.
}}}
Where the offending line looks like:
{{{
utils/genprimopcode/dist/build/Syntax.o : C:/Program\ Files/Haskell\
Platform/2010.1.0.0/lib/base-4.2.0.0/Data/List.hi
}}}
To work around the issue you can install Cygwin make 3.80 from http://www
.go-mono.com/archive/helper/make-3.80-1.tar.bz2 or
http://www.cmake.org/files/cygwin/make.exe to replace the Cygwin installed
make executable.
The right fix is for GHC to use cygpath before putting any Windows paths
in makefiles.
