* sysdeps/powerpc/bits/wordsize.h: New file. * sysdeps/powerpc/fpu/bits/mathinline.h (lrint, lrintf): Change long array to int array for 32-/64-bit compatibility. 2002-09-20 Roland McGrath <roland@redhat.com> * login/programs/utmpdump.c: Don't include <error.h>, <errno.h>. * sysdeps/generic/utimes.c (__utimes): Don't check TVP for null. Reported by Bruno Haible <bruno@clisp.org>. * sysdeps/generic/ifreq.h (__ifreq): Compute termination condition before doubling RQ_LEN. * sysdeps/unix/sysv/linux/ifreq.h (__ifreq): Likewise. Reported by Bruno Haible <bruno@clisp.org>. 2002-09-18 Bruno Haible <bruno@clisp.org> * login/logout.c (logout): Don't assume ut_time has the same size as a time_t. * login/logwtmp.c (logwtmp): Likewise. * sysdeps/pthread/configure: New file, moved here from linuxthreads/sysdeps/unix/sysv/linux/configure.
