From libelf subdir. * Makefile.am (euincludedir): Define. (euinclude_HEADERS): Add elf-knowledge.h. 2003-09-24 Ulrich Drepper * elf.h: Define some PT_IA_64_HP_* constants. 2003-09-23 Jakub Jelinek * libelfP.h (struct Elf): Move state.elf64.sizestr_offset after state.elf64.scnincr to match state.elf{,32}. 2003-08-12 Ulrich Drepper * elf32_updatefile.c (__updatemmap): When writing back file where some sections have not been read in, count their sizes based on the section header. 2003-08-11 Ulrich Drepper * Moved to CVS archive.
