/*
  Default solver configuration: In any environment, clp is the default if you
  do nothing.
 
  The necessary definitions will be handled by the configure script (based on
  the value specified for --with-osicbc-default-solver) in any environment
  where configure is available. The results can be found in inc/config_osi.h,
  which is created during configuration from config_osi.h.in and placed
  in the build directory.
 
  In an environment which does not use configure (MS Visual Studio, for example)
  the preferred method is to edit the definitions in inc/OsiConfig.h. The
  symbols are left undefined by default because some older environments (e.g.,
  MS Visual Studio v7 or earlier) will not accept an #include directive which
  uses a macro to specify the file. In such an environment, if you want to use
  a solver other than OsiClp, you'll need to make the changes here.
