2002-05-17 Jeff Johnston <jjohnstn@redhat.com> * Makefile.am: Copy and install headers from sys/machine/include directory. Also pass $toollibdir to lower-level directories. * Makefile.in: Regenerated. * libc/include/stdio.h[!_REENT_ONLY]: Change stdin, stdout, and stderr to use _REENT macro instead of _impure_ptr directly. * libc/include/sys/config.h[__i386__][__linux__]: Define __DYNAMIC_REENT__. * libc/include/sys/reent.h[!_REENT_ONLY]: Change _REENT macro to be call to __getreent() function if !__SINGLE_THREAD__ and __DYNAMIC_REENT__ is set. * libc/reent/Makefile.am: Add support for getreent.c. * libc/reent/Makefile.in: Regenerated. * libc/string/strerror.c: Add check if EOPNOTSUPP and ENOTSUP are same. * libc/sys/linux/Makefile.am: Add support for new files. * libc/sys/linux/configure.in: Add $EXTRA_DIRS variable. * libc/sys/linux/Makefile.in: Regenerated. * libc/sys/linux/configure: Ditto. * libc/sys/linux/io.c: Add poll syscall. Also weak-alias __close, __read, __write, __poll, __open, __lseek, __fcntl from their __libc_ counterparts. * libc/sys/linux/io64.c: Add __libc_ prefix to lseek64 and open64 and weak-alias to regular names. * libc/sys/linux/pread64.c: Rename to __libc_pread64 and weak-alias to pread64 and __pread64. * libc/sys/linux/process.c: Weak_alias __libc_getpid to __getpid. * libc/sys/linux/pwrite64.c: Rename to __libc_pwrite64 and weak-alias to pwrite64. * libc/sys/linux/sched.c: Weak-alias __libc_sched_getparam, __libc_sched_getscheduler, __libc_sched_get_priority_max, __libc_sched_get_priority_min, and __libc_sched_setschedule to name with __ instead of __libc_. * libc/sys/linux/siglongjmp.c: Include <machine/weakalias.h>. Rename siglongjmp to __libc_siglongjmp and weak-alias to siglongjmp. Call __libc_longjmp instead of longjmp, from __libc_siglongjmp. * libc/sys/linux/signal.c: Rename raise to __libc_raise and weak-alias to raise. * libc/sys/linux/socket.c: Weak-alias __libc_connect to __connect and __libc_send to __send. * libc/sys/linux/time.c: Weak-alias __libc_gettimeofday to __gettimeofday. * libc/sys/linux/wait.c: Rename wait to __libc_wait and weak-alias it to wait. Rename wait3 to __libc_wait3 and weak-alias it to wait3. * libc/sys/linux/include/setjmp.h: Use __jmp_buf in sigjmp_buf type and typedef __jmp_buf to jmp_buf. * libc/sys/linux/machine/i386/Makefile.am: Add syscalls.c and setjmp.S. * libc/sys/linux/machine/i386/Makefile.in: Regenerated. * libc/sys/linux/machine/i386/crt0.c: Add support to clear .bss section. * libc/sys/linux/machine/i386/socketcall.h: Change to use __libc_ prefix for function macros and then use weak_alias() to regular names. * libc/sys/linux/machine/i386/syscall.h: Ditto. * libc/sys/linux/sys/errno.h: Define EOPNOTSUP to be ENOTSUP. * libc/sys/linux/sys/stdio.h: Define _flockfile and _funlockfile to be flockfile() and funlockfile() respectively. * libc/sys/linux/sys/types.h * libc/reent/getreent.c: New file. * libc/sys/linux/flockfile.c: Ditto. * libc/sys/linux/funlockfile.c: Ditto. * libc/sys/linux/getreent.c: Ditto. * libc/sys/linux/pread.c: Ditto. * libc/sys/linux/pwrite.c: Ditto. * libc/sys/linux/raise.c: Ditto. * libc/sys/linux/system.c: Ditto. * libc/sys/linux/tcdrain.c: Ditto. * libc/sys/linux/machine/i386/i386mach.h: Ditto. * libc/sys/linux/machine/i386/setjmp.S: Ditto. * libc/sys/linux/machine/i386/syscalls.c: Ditto. * libc/sys/linux/machine/i386/weakalias.h: Ditto. * libc/sys/linux/machine/i386/include/setjmp.h: Ditto.
