Program Listing for File fileoffsetbits.h

// DQ (3/12/2006): This is included here as specified in the Autoconf manual (using <> instead of "")
// We have also abandoned the ifdef HAVE_CONFIG_H cpp conditional use of rose_config.h as well.
// 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).
// #include <rose_config.h>

// DQ (4/21/2009): Error checking to avoid difficult to debug ODR violations on 32-bit systems.

// header includes the STL string header which will include sys/stat.h first.
