// This is placed here in sage3.h instead of in rose.h because it needs to always be seen even 
// by internal ROSE files that only include sage3.h.

// DQ (10/14/2010): We don't want to include this into our header file system
// since then users will see the defined macros in our autoconf generated 
// config.h (which we generate as rose_config.h to avoid filename conflicts).
// This fixes the problem that causes macro names to conflict (e.g. PACKAGE_BUGREPORT).
