been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied. Well, I'm finally am
happy with the new config system, so here it is. This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.
I have thus far updated only x86. I'll be updating the other
architectures shortly.

without custom stream support. In that case, it is necessary to do
a va_copy. Note: The affected code is not built in the stock config.
Also, make sure each va_copy has a matching va_end, as required by C99.

the cookie pointer was set to NULL as a debugging aid. However,
some of the perl 5.8 test rely on being able to close stderr and
still try writing to it. So now, the cookie pointer and handler
function pointers are set to that it is a "normal" file with a
file descriptor of -1.
Note: The cookie pointer is reset to NULL if the FILE struct is
free'd by fclose.

sense to exclude it, gcc always supports long long, and we never
fully excluded long long anyways (off64_t for example).

One involving %o and one involving %f.

I think they're fixed now (I've run a few tests).
Note: __fsetlocking() is not threadsafe... but glibc's doesn't appear to
be either.

needlessly. To do so increases the generated code size with bcc.
Eliminate duplicate define warnings in wstring.c.
Fix potentially broken preprocessor comparisons. The preprocessor
converts integers to maximal signed type, so inequality comparisons
involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX
were potentially broken.

a 3.0.4 version of the sh-linux-gcc compiler.

This falls under undefined behavior wrt ANSI/ISO C99, but
SUSv3 seems to treat it as a no-op and it occurs in some apps.
Fixed a problem with _stdio_fwrite() not checking for underlying
write() failures.
Fixed both _stdio_fwrite() and _stdio_fread() to make sure that
the putc and getc macros were disabled if the stream was in
and error state.
The above changes should take care of a problem initially reported
by "Steven J. Hill" <sjhill@realitydiluted.com>.

Fix a few bugs in wchar.c.
Modifications for bcc/elks support.

standards. Temporarily added a utility function to wrap Erik's strerror_r
so that "Unknown error xxx" strings can be generated for errno's which
cause strerror_r to fail. That utility function will eventually be merged
in with the strerror/strerror_r functions when I change over to optionallly
mmap'ing the system error strings to provide for lower mem comsumption on
non-MMU platforms, as well as locale-specific system error messages.

The writer for the stream returned by open_memstream was supposed to
keep the buffer nul-terminated. I apparently left out a statement.
|
|
non-NULL terminated string problem that could result from the use
of open_memstream(). Manuel may have a better solution, but this
one works for me, since with this plus the popen fix I can now run
things like gdb properly. Thanks Rik!
|
|
There is a minor bug in the implementation of popen(). In the case
where the file descriptor returned from its call to pipe() is the same
as the file descriptor that it is meant to be (where the dup2() branch
is not taken), the end of the pipe is still closed by close(reading)
even though it shouldn't be.
Thanks Ted!

port. Also, explicitly use the macro versions of isdigit and isspace in the
printf and scanf code.

auto-transition, we fail the operation. This is different than glibc's
apparent behavior for writing of clearing the read buffer and still
failing the write without setting the stream's error flag.
Also, change a number of "errno = xxx" assignments to use __set_errno().
Also, change setvbuf(file, NULL, _IO{LF}BF, 0) behavior to more closely
match glibc's by keeping the current buffer and only changing the buffering
mode. Update setlinebuf() in the process to match the man page behavior.

EINTR [when] the fclose() function was interrupted by a signal". But
looking in the current uClibc stdio.c for some bizarre reason we had a
special case where when errno was EINTR, we would keep on trying
instead. Doh! Fix that,

from abort() and from _exit(), we need to ensure that flushing
