Hmm, the relevant ChangeLog entry is: 2000-10-16 Chris Demetriou * mips.h (E_MIPS_ARCH_32): New constant. (E_MIPS_MACH_MIPS32, E_MIPS_MACH_MIPS32_4K): Replace the former with the latter. * mips.h (E_MIPS_ARCH_5, E_MIPS_ARCH_64): New definitions. * mips.h (E_MIPS_MACH_SB1): New constant. Patches went in with two commits on Dec 1st and 2nd, 2000: http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/include/elf/mips.h.diff?r1=1.8&r2=1.9&cvsroot=src http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/include/elf/mips.h.diff?r1=1.9&r2=1.10&cvsroot=src Maciej -- + Maciej W.
