Update.
2003-03-19 Ulrich Drepper <drepper@redhat.com> * Makefile (distribute): Add include/atomic.h and bits/atomic.h. * include/atomic.h: New file. * sysdeps/i386/i486/bits/atomic.h: New file. * sysdeps/x86_64/bits/atomic.h: New file. * sysdeps/s390/bits/atomic.h: New file. * sysdeps/sh/bits/atomic.h: New file. * sysdeps/ia64/bits/atomic.h: New file. * sysdeps/powerpc/bits/atomic.h: New file. * sysdeps/generic/bits/atomic.h: New file. * sysdeps/i386/i486/atomicity.h: Removed. * sysdeps/x86_64/atomicity.h: Removed. * sysdeps/s390/s390-32/atomicity.h: Removed. * sysdeps/s390/s390-64/atomicity.h: Removed. * sysdeps/ia64/atomicity.h: Removed. * sysdeps/powerpc/powerpc32/atomicity.h: Removed. * sysdeps/powerpc/powerpc64/atomicity.h: Removed. * elf/dl-profile.c: Use atomic.h instead of atomicity.h. Adjust use of macros from atomicity.h to new names and semantics. * gmon_mcount.c: Likewise. * malloc/set-freeres.c: Likewise. * nscd/cache.c: Likewise. * stdlib/cxa_finalize.c: Likewise. * sysdeps/unix/sysv/linux/getsysstats.c: Likewise. * sysdeps/mips/ieee754.h: New file, suitable to replace both * stdlib/strtod.c (INTERNAL): While eating trailing zeros handle
