Thu Dec 12 03:32:21 1996 Ulrich Drepper <drepper@cygnus.com> * libio/_G_config.h: Add definition of _G_int16_t, _G_int32_t, _G_uint16_t, _G_uin32_t, _G_HAVE_BOOL, _G_HAVE_MMAP, and _G_ARGS. Change libio buffer handling to allocate internal buffers using mmap if possible. * libio/filedoalloc.c (_IO_file_doallocate): Change call to ALLOC_BUF. * libio/genops.c (_IO_setb, _IO_default_finish): Change call to FREE_BUF. (_IO_default_doallocate): Change call to ALLOC_BUF. * libio/libioP.h: Change definition of ALLOC_BUF and FREE_BUF to use mmap/munmap when possible. * libio/memstream.c: Don't use ALLOC_BUF, but directly malloc. * libio/vasprintf.c: Likewise. Patch by HJ Lu. * libio/libio.h: Define NULL as __null only for gcc-2.8 and up. * libio/libioP.h: Likewise. * libio/fileops.c (_IO_file_read, _IO_file_write): Don't restart syscall when EINTR was returned. Necessary for POSIX.1. * libio/strops.c (_IO_str_overflow): Add cast to prevent warning. * new-malloc/malloc.c (heap_trim): Correctly place parentheses to prevent warnings. * nis/Makefile: Remove rules for bsd-tools which are not part of glibc. Patch by Thorsten Kukuk. * nis/ypclnt.c: Add prototype for xdr_free. Add const to first parameter for __yp_bind. * nis/nss_compat/compat-pwd.c (getpwent_next_netgr, getpwent_next_nis, getpwent_next_file): Variable `p2len' must have type size_t. * nis/nss_nis/nis-alias.c: Add casts to prevent warnings. * nis/nss_nis/nis-ethers.c: Likewise. * nis/nss_nis/nis-grp.c: Likewise. * nis/nss_nis/nis-hosts.c: Likewise. * nis/nss_nis/nis-network.c: Likewise. * nis/nss_nis/nis-proto.c: Likewise. * nis/nss_nis/nis-pwd.c: Likewise. * nis/nss_nis/nis-rpc.c: Likewise. * nis/nss_nis/nis-service.c: Likewise. * nis/nss_nis/nis-spwd.c: Likewise. * nis/rpcsvc/yp_prot.h (ypreq_key): Change type of members to `const char *'. (ypmaplist): Change member names to `map' and `next' and provide #defines for old names. Patch by Thorsten Kukuk. * nss/nss_files/files-parse.c (parse_line, parse_list): Change type for `datalen' parameter to size_t. * shsdow/lckpwdf.c: Use fcntl forlocking, not flock. * stdio-common/printf.c [USE_IN_LIBIO]: Provide alias _IO_printf for printf. * stdio-common/sscanf.c [USE_IN_LIBIO]: Provide alias _IO_sscanf for sscanf. Patch by HJ Lu. * stdio-common/tmpfile.c: Update copyright. * stdio-common/vfscanf.c: Correctly handle EINTR error from fgetc function. Don't eat white space for `C' format. * stdlib/tst-strtol.c [~0UL != 0xffffffff]: Fix typo in test data. * sysdeps/generic/abort.c: Update copyright. De-ANSI-declfy. * sysdeps/i386/abort.c: Removed. This version does not use signal SIGABRT. * sysdeps/i386/fpu/__math.h: Define __NO_MATH_INLINES if not using gcc-2.8 or up. Patch by HJ Lu. * sysdeps/posix/tempname.c: Test for error but EEXIST after open call. If EMFILE, ENFILE, or EINTR return with error. Wed Dec 11 14:43:52 1996 Ulrich Drepper <drepper@cygnus.com> * gnu-versions.h: Set _GNU_OBSTACK_INTERFACE_VERSION back to 1. We are compatible again. * new-malloc/obstack.h (struct obstack): Add back alloc_failed bit even though it is not used. * malloc/obstack.h: Likewise. * new-malloc/obstack.c (_obstack_begin, _obstack_begin_1): Initialize alloc_failed bit to 0. * time/strftime.c: Extend for Emacs' needs. Recognize field width, %P format and `0' modifier. Tue Dec 10 21:20:44 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makerules (make-link): Don't discard exit codes of intermediate commands. Always use rellns-sh if symbolic links are available. Tue Dec 10 20:09:51 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/netinet/in.h: Enclose #include <linux/in.h> in __BEGIN_DECLS/__END_DECLS to avoid linkage conflict of ntohs etc. in <asm/byteorder.h>.
