* elf/linux-compat.c: New file. * elf/Makefile (distribute): Add linux-compat.c. (generated): Add librtld.so. [$(config-os)=linux*] (extra-objs): Add linux-compat.so. [$(config-os)=linux*] (extra-objs): Add ld-linux.so.1. (librtld.so): New target. (ld.so, ld-linux.so.1): Make from librtld.so. * elf/rtld.c (dl_main): Instead of weak call to _dl_compat_init, call our own DT_INIT if we have one (and then clear it). (__dgettext): New weak function. * intl/localealias.c (read_alias_file): Avoid sprintf; use memcpy by hand instead. * sysdeps/generic/_strerror.c (_strerror_internal): Use _itoa instead of snprintf. * sysdeps/mach/_strerror.c (_strerror_internal): Don't write BUF[BUFLEN]. * elf/rtld.c (rtld_map): New static variable. (_dl_start): Use a differently named local BOOTSTRAP_MAP for the bootstrapping. Then copy data into `rtld_map'. (dl_main): Finish filling in rtld_map and link it into the chain, instead of allocating a new structure. (dl_main): Call _dl_compat_init if it is defined (use weak ref). * elf/dlsym.c: Fix last change: move REF out of `doit'. control. using it. and cwdir ports. functions. these. $(libdir)(rtld-installed-name). leading zeroes. in the rhs. pattern rule. never know. (fork): Use symbol_set_* macros for _hurd_fork_locks. * sysdeps/unix/sysv/sysv4/linux/i386/sysdep.S (__syscall_error): instead of unix/sysv. -dynamic-linker. (__printf_fp): Last arg ARGS is now `const void **const'; locale/C-ctype.c. * sysdeps/mach/hurd/sigsuspend.c: Likewise. * sysdeps/mach/hurd/mips/sigreturn.c: Likewise. alias gethostname. setitmr setpgrp (_S_msg_get_exec_flags, _S_msg_set_exec_flags, (abort_thread, abort_rpcs): Take same new arg and pass it through.
