Thu Aug 30 07:43:12 PDT 2007 Duncan Coutts <duncan@haskell.org> * Make checking program versions not produce error spew Redirect stderr to /dev/null (or NUL on windows) and throw an exception like rawSystemExit does rather than calling die which prints an unhelpful message before throwing an exception. It's not an overall failure to not be able to establish the version of a program, since we check later if we actually have any requirement for any particular version anyway. So for example this makes running configure with an old version of c2hs that doesn't grok --numeric-version not produce unhelpful output that make people think that configure failed.
