cat <<EOD

The MSYS source is prepared in 

  $winpath

The source has been unpacked, checked in to git, and all necessary
patches have been applied.  You can verifying this by looking at
the git history.

Unfortunately, there is no automatic way to build msys-1.0.dll from
the source, so you now need to manually continue as described on:

   http://www.mingw.org/MinGWiki/index.php/Build%20MSYS

In a properly setup MSYS, you can start the build shell by

   msysdvlpr

In the newly opend build shell you need to run:

   cd $winpath
   mkdir bld
   cd bld
   ../source/configure --prefix=/usr
   make

The replacement for msys-1.0.dll will be created as

   i686-pc-msys/winsup/cygwin/new-msys-1.0.dll

You need to copy the new dll to your msysgit directory.  Note that
this is only possible if no msysgit bash is open.  Otherwise, Windows
refuses to replace the msys-1.0.dll.
