|
|
* elf/dl-open.c (_dl_open): Force an indirect call for
_dl_relocate_object so there is no chance a PLT fixup will be done
and clobber _dl_global_scope before our call happens.
* sysdeps/i386/fpu/__math.h (tan): Correct output constraint from =u
to =t; must operate on top of fp reg stack, not second from top.

of, not the ones he is _not_ a member of.
* nss/nsswitch.c (known_compare): Make known_compare() a static
instead of a local function. The latter are difficult to debug
and slow to execute on certain platforms.

(vfprintf): While determining length of multibyte string don't
try to be clever in determining characters to use for first
call.
Add real implementation of multibyte<->wide char conversion
functions. The functions always convert between the fixed wide
char format (ISO 10646 in UCS4) and the UTF8 representation of
this character set. Conversion between the currently used
8bit character set and ISO 10646 will not take place. This is
what iconv() is for.

dummy definition.

element of `mbstate_t' for initial state.

encoded string to UCS4 string.
* wcsmbs/wcrtomb.c: Replace dummy implementation. Convert UCS4
character to UTF8 encoded form.
* wcsmbs/wcsrtombs.c: Replace dummy implementation. Convert UCS4
encoded string to UTF8 encoded form.

notice an insufficient Linux version.

* sysdeps/unix/sysv/linux/configure.in: Check for Linux 2.0.1 headers,
instead of 2.0 headers.
|
|
* sysdeps/gnu/errlist.awk: Undo mib's bogus changes. The

error is 0. The "placeholder" entries recently added to
errno.texi convert to zero since `???/' is at the front of them.
* sysdeps/gnu/errlist.awk (errnoh): Likewise.
* sysdeps/stub/setdomain.c (setdomainname): Declare NAME parm
__const to conform with unistd.h.
* posix/regex.c (re_comp, re_exec): Use weak_function as
keyword in function defns instead of weak_symbol (NAME) after
