* sysdeps/i386/dl-machine.h (elf_machine_rel): Check for mismatch in size for copy relocation. * sysdeps/m68k/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/sparc/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/powerpc/dl-machine.h (elf_machine_rela): Likewise. Patch by Roland McGrath <roland@gnu.ai.mit.edu>. 1997-05-06 13:25 H.J. Lu <hjl@gnu.ai.mit.edu> * stdio-common/bug4.c (main): Use /tmp/bug4.test for concurrency with other tests. * stdio-common/bug3.c (main): Use /tmp/bug3.test for concurrency with other tests. * sunrpc/svc_run.c: svc_exit): New, defined. (svc_run): Test for svc_stop variable. * sunrpc/rpc/svc.h (svc_exit): New, declared. 1997-05-03 08:47 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * math/libm-test.c (test_not_exception): Don't mix the internal exception flags with the host defined FE_* values.
