1997-08-29 02:36 Ulrich Drepper <drepper@cygnus.com> * Makefile (version-info.h): Use ISO form for the date. * catgets/catgetsinfo.h: Include <bits/libc-lock.h>. (struct catalog_obj): Add lock field. (__open_catalog): Remove second parameter from prototype. * catgets/catgets.c (catopen): Initialize lock field. (catgets): Don't pass second parameter to __open_catalog. * catgets/gencat.c: Initialize lock field and don't pass second parameter to __open_catalog. * catgets/open_catalog.c (__open_catalog): Decide about use of path by examining path in struct, not based on extra argument. Acquire a the lock before trying to load the catalog and release it before returning. * csu/Makefile (abi-tag.h): Make sure target directory exists. * io/Makefile (headers): Add bits/poll.h. * io/sys/poll.h: Remove definitions of POLL* constants. Include <bits/poll.h>. * sysdeps/generic/bits/poll.h: New file. * sysdeps/unix/sysv/linux/bits/poll.h: New file. * sysdeps/unix/sysv/linux/m68k/bits/poll.h: New file. * sysdeps/unix/sysv/linux/mips/bits/poll.h: New file. * sysdeps/unix/sysv/linux/sparc/bits/poll.h: New file. * libio/fileops.c (_IO_file_read, _IO_file_write): Remove dead code. * malloc/obstack.c: Add casts to keep very verbose compilers on 64bit machine quiet. * nss/Makefile (libnss_db.so): Find libdb.so in db2 directory. 1997-08-28 17:30 Ulrich Drepper <drepper@cygnus.com> * catgets/catgets.c (catopen): Correctly determine length of string in NLSPATH evironment variable. Patch by HJ Lu <hjl@gnu.ai.mit.edu>. 1997-08-27 23:19 Richard Henderson <rth@cygnus.com> * sysdeps/generic/dl-sysdep.c (DL_FIND_ARG_COMPONENTS): Provide default macro to track down arguments from stack start. (_dl_sysdep_start): Use it. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Truncate to simply providing a special DL_FIND_ARG_COMPONENTS and including the next file up the line. * sysdeps/powerpc/e_sqrt.c: Move contents to w_sqrt.c and provide stub. * sysdeps/powerpc/e_sqrtf.c: Likewise. * sysdeps/powerpc/s_copysignf.S: Provide empty file; symbol is with the double precision version. * sysdeps/powerpc/s_fabsf.S: Likewise. * sysdeps/powerpc/s_isnanf.S: Likewise.
