// Author(s):    nickg

// Contributors: nickg

// Date:         2000-11-20

// Purpose:      Define MIPS ELF support

// Description:  This file contains definitions for configuring the dynamic

//               loader to deal with the MIPS specific parts of the ELF

//               file format.

//              

// Usage:

//              #include <cyg/loader/mips_elf.h>

//              ...

//
