Update.
1998-02-16 17:33 Ulrich Drepper <drepper@cygnus.com> * elf/rtld.c (dl_main): Recognize --library-path parameter and pass value (or NULL) to _dl_init_paths. * elf/dl-load.c (_dl_init_paths): Change to take one parameter, replacing local variable llp. If llp is NULL examine LD_LIBRARY_PATH environment variable. * elf/link.h: Change prototype for _dl_init_paths. * elf/dl-support.c: Pass NULL in _dl_init_paths call. * localedata/Makefile (distribute): Add test files. 1998-02-17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * localedata/tests/{test1.cm, test2.cm, test3.cm, test4.cm, test1.def, test2.def, test3.def, test4.def}: Simple input files for localedef. Contributed by Yung-Ching Hsiao <yhsiao@cae.wisc.edu>. * localedata/Makefile (tests): Call tst-locale.sh. * localedata/tst-locale.sh: New file, regression tests for some localedef problems. 1998-02-15 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nss_nisplus/nisplus-alias.c: Use __stpncpy. * nis/nss_nisplus/nisplus-hosts.c: Make sure buffer is always NUL terminated. * nis/nss_nisplus/nisplus-network.c: Likewise. * nis/nss_nisplus/nisplus-proto.c: Likewise. * nis/nss_nisplus/nisplus-rpc.c: Likewise. * nis/nss_nisplus/nisplus-service.c: Likewise. Add more changes from TI-RPC 2.3 for rpcgen to fix include/C++ bug and support generating thread safe RPC code. * sunrpc/rpc_main.c: Add changes. * sunrpc/rpc_clntout.c: Likewise. * sunrpc/rpc_cout.c: Likewise. * sunrpc/rpc_hout.c: Likewise. * sunrpc/rpc_parse.c: Likewise. * sunrpc/rpc_sample.c: Likewise. * sunrpc/rpc_scan.c: Likewise. * sunrpc/rpc_svcout.c: Likewise. * sunrpc/rpc_util.c: Likewise. * sunrpc/rpc_util.h: Add new structs and prototypes. * sunrpc/proto.h: Remove prototypes for static functions. 1998-02-15 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * locale/programs/ld-messages.c (messages_finish): Don't skip error checking when being quiet. * locale/programs/ld-ctype.c (ctype_finish): Likewise. (set_class_defaults): Likewise. * locale/programs/charmap.c (parse_charmap): Likewise. * locale/programs/ld-collate.c (collate_finish): Likewise. * locale/programs/ld-monetary.c (monetary_finish): Likewise. * locale/programs/ld-time.c (time_finish): Likewise. * locale/programs/locfile.c (write_locale_data): Likewise. * locale/programs/ld-ctype.c (ctype_class_to): Silently ignore unknown characters and empty ranges. * locale/programs/ld-collate.c (collate_order_elem): When processing an ellipsis properly form a linked list in the result table, fix typo when allocating ordering array. [PR libc/419] 1998-02-13 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/Makefile (ld-map): Define. (rtld-ldscript): Define. Change all `$(objpfx)rtld-ldscript' to `$(rtld-ldscript)'. ($(objpfx)ld.so): Combine the two versions of this rule. Depend on $(ld-map). (rtld-link): Combine the two versions of this definition. Fixed to make it work when no symbol versioning is used. 1998-02-16 Ulrich Drepper <drepper@cygnus.com> * Makeconfig (build-program-cmd): Use --library-path parameter to ld.so instead of environment variable. * sunrpc/Makefile (rpcgen-cmd): Don't use -$ parameter. * sunrpc/rpc_main.c: Remove support for -$$ option again. 1998-02-16 Andreas Jaeger <aj@arthur.rhein-neckar.de> * Make-dist: Respect with-cvs setting. * MakeTAGS (all-pot): Likewise. * sysdeps/sparc/sparc32/Makefile: Likewise. * sysdeps/mach/hurd/Makefile: Likewise. * stdlib/Makefile: Likewise. * posix/Makefile: Likewise. * intl/Makefile: Likewise. * po/Makefile (linguas): Likewise
