Update.
1999-08-09 Scott Bambrough <scottb@netwinder.org> * elf/elf.h: Added definition of ELFOSABI_ARM. * elf/dl-load.c (_dl_map_object_from_fd): Use VALID_ELF_HEADER, VALID_ELF_OSABI, VALID_ELF_ABIVERSION to decide whether an object's header and ABI values are acceptable. (VALID_ELF_HEADER): New macro; provide default definition. (VALID_ELF_OSABI): New macro; provide default definition. (VALID_ELF_ABIVERSION): New macro; provide default definition. * sysdeps/arm/dl-machine.h Define ARM specific versions of VALID_ELF_HEADER, VALID_ELF_OSABI, VALID_ELF_ABIVERSION. 1999-08-09 Andreas Schwab <schwab@suse.de> * inet/tst-ipnode.c (main): Don't compare integer with NULL. 1999-08-09 Thorsten Kukuk <kukuk@suse.de> * sunrpc/svc_run.c (svc_run): Free my_pollfd. 1999-08-09 Andreas Schwab <schwab@suse.de> * sunrpc/svc.c (svc_getreq_poll): Fix argument of xprt_unregister.
