* sysdeps/mach/hurd/Makefile ($(link-rpcuserlibs)): Don't append
options after $(build-module), which is no longer a single command. (LDFLAGS-link-rpcuserlibs): New variable to hold those options. (LDFLAGS-libmachuser-link.so, LDFLAGS-libhurduser-link.so): New variables using it. Reported by Mark Kettenis <kettenis@gnu.org>. 2001-03-11 Roland McGrath <roland@frob.com> * elf/rtld.c (dl_main): Add cast to quiet warning. * elf/dl-load.c (_dl_map_object_from_fd): Likewise. * iconv/gconv_conf.c (__gconv_get_path): Likewise. (__gconv_read_conf): Likewise. * iconv/gconv_db.c (gen_steps): Likewise. (__gconv_find_transform): Likewise. * locale/programs/charmap-dir.c (fopen_uncompressed): Likewise. (fopen_uncompressed): Use const in second argument's type. 2001-03-11 Roland McGrath <roland@frob.com> * sysdeps/mach/hurd/dl-sysdep.c (__writev): New function. * mach/mach_error.h: Fix ancient #endif syntax. * hurd/hurdmalloc.c: Likewise. * sysdeps/generic/atomicity.h (exchange_and_add, atomic_add, compare_and_swap): Add volatile qualifier to first arg, to bring these prototypes in line with all the other implementations. Add a #warning to remind the builder that these are not atomic. 2001-03-04 Roland McGrath <roland@frob.com> * hurd/vpprintf.c (vpprintf) [USE_IN_LIBIO]: Use innermore first member of TEMP_F so its type is _IO_FILE * as expected. * hurd/fopenport.c (seekio): Conditionalize type of POS argument on [USE_IN_LIBIO]. Check the value for overflow, since for libio it might exceed off_t's range. 2001-02-25 Roland McGrath <roland@frob.com> * sysdeps/mach/hurd/sysd-stdio.c (__stdio_reopen): Use prototype. * sysdeps/unix/bsd/getpt.c (__posix_openpt): Likewise. * sysdeps/mach/hurd/i386/intr-msg.h (SYSCALL_EXAMINE): Make this a macro instead of an inline function, (MSG_EXAMINE): Likewise. * hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS_1): Remove extraneous ##. * hurd/get-host.c: Include <string.h> for decls of built-ins. * hurd/hurdchdir.c: Likewise. * sysdeps/mach/hurd/i386/sigreturn.c: Likweise. * sysdeps/mach/hurd/opendir.c: Likewise. * mach/mach_init.c: Include <unistd.h> for _exit decl. * mach/errsystems.awk: Give output file a trailing newline. * mach/Machrules (MIG): Prepend CC='${CC}' to the mig command, so that the script will use our compiler for the cpp stage. With --enable-all-warnings we get a whole bunch of warnings, and these are just a few fixes; there are more needed to silence it. * mach/mach/mig_support.h (__mig_strncpy, mig_strncpy): Add extern decls before extern inline defns to quiet gcc warning. * hurd/hurd/threadvar.h (__hurd_threadvar_location_from_sp): Likewise. * sysdeps/mach/i386/machine-sp.h (__thread_stack_pointer): Likewise.
