The attached patch works around some compilation failures on
ia64 caused by the use of the C preprocessor ## operator, and
allows the ia64 default configuration to build again -- or, at
least get as far as an x86 build does (the current source tree
has some problems compiling because of conflicting type
declarations for __kernel_dev_t).

again, this makes the non-threaded case compile again. I have no idea
if this is the proper fix, I'm just tired if it not compiling for two
weeks.

(No idea if this is the right fix but it's something for now.)

Import INTERNAL_SYSCALL macro for i386 from glibc.
Use above macro in posix_fadvise implementation if an arch defines it.

When I imported INLINE_SYSCALL, etc. from glibc, I just copied whole
macros for each ABI. Actually, except for argument type (long
vs. long long), internal_syscall[0-4] are identical for all ABI, and
internal_syscall[5-6] for N32/N64 are identical for N32/N64.
And I just disabled FORCE_FRAME_POINTER since it had caused build
failure, but including <alloca.h> can solve it.
Here is a patch to handle these issues, plus asm/__asm__ and
volatile/__volatile__ conversion.
Thanks for Peter S. Mazinger who did basic work of this cleanup.

clean up E500 math support somewhat.

protect its use by #ifdef INTERNAL_SYSCALL since not all
arch's has INTERNAL_SYSCALL.
All arch's not having INTERNAL_SYSCALL in
libc/sysdeps/linux/<arch>/bits/syscalls.h should get an update
from glibc.

Lets hope I didn't break something.

Current ucontext_t does not match with kernel's definition. Also, on
N32 ABI, we can not use kernel's struct sigcontext since kernel's
sizeof(long) and user's sizeof(long) is differ.
For both data structure, just importing header files from recent glibc
fixes the mismatch. So here is a patch importing sys/ucontext.h and
bits/sigcontext.t from glibc-2.5.

gcc barf otherwise.

This patch imports INLINE_SYSCALL, etc. from glibc-2.5 ports and
implements _syscall[0-7] by using them, like arm and powerpc.
I think this patch does not change functionality, but gives better
__SYSCALL_CLOBBERS for N32/N64.

Hi. I have found a bug in realpath that did not allow me to use it with
symlinks. Although I am using 0.9.28.1, the bug is present in 0.9.28 and
also in the trunk.
I attach a suggested patch. Please let me know if the solution is correct.

I'm seeing a hang in applications that open and close files with a
non-threaded uClibc. There is code in fclose() to remove a file handle from
_stdio_openlist however it's commented out, allegedly because it is dead.
_stdio_openlist is used in several places, including _stdio_term when a
program exits. fclose() frees the struct, so I don't see how the code can
possibly be redundant.
In the __UCLIBC_HAS_THREADS__ && __STDIO_BUFFERS case the file is removed from
_stdio_openlist by __STDIO_OPENLIST_DEC_USE.
The attached patch fixes this bug be re-enabling the code.

__USE_FILE_OFFSET64 is defined. This was the case for all
architectures except those that use packed structures by default
(i.e., CRIS).

I have successfully made gethostbyname_r(), res_init(), and gethostid() fully
reentrant. In addition, I have added a NULL check to inet_aton(). This is
where SEG FAULTs were coming from when gethostbyname_r() was called.

Hi Erik,
Thanks for all your great work. I found a set of bugs in
resolv.c . Basically, there is code that looks like:
BIGLOCK;
__nameserversXX=__nameservers;
__nameserverXX=__nameserver;
BIGUNLOCK;
i = __dns_lookup(dname, type, __nameserversXX, __nameserverXX, &packet, &a);
which is a problem because the declarations are
int __nameservers;
char * __nameserver[MAX_SERVERS];
int __searchdomains;
char * __searchdomain[MAX_SEARCH];
so you can see that __nameserver is a pointer. Copying the
pointer to __nameserverXX doesn't protect the global variable
space. I have attached a patch and the new file. I hope you
will incorporate these bug fixes. I spent quite a bit of time
tracking them down.
Many thanks,
Ron
