Fork

Remove obsolete files tell.c and getdents.c

Stub out an initial version. Manuel will be writing
some code to autogenerate this stuff...

Don't even threaten to include asm/* stuff

Don't include asm/unistd.h

Step one in a process to ween ourselves off of using asm/unistd.h.
This will break the build for a bit.

Fix syntax error in comment.

Make these PIC and _LIBC_REENTRANT compatible.

For now, we need to explicitly make clean in libc/unistd (sysconf stuff)
and libc/sysdeps/linux/common (unified syscall stuff).

Yes... I forgot to update bits/dirent.h for the other archs. :-(

ANSI/ISO specifies that no library function sets errno to 0.

Looks like we lost clearing errno

Change to allow compiling against unconfigured kernels. Creates
symlink to include/asm-${arch} instead of include/asm.

Note need to fix scandir.c's dynamic memory handling.

Remove simulated d_type support for getdents and the dirent struct, and use
the straight getdents syscall instead of the wrapper (which leaked memory).

Add in missing syscalls.h for powerpc

Fixed vfork so the child doesn't trash the parents return address.

Make PIC a config option

This adds in support for PIC on x86. Unfortunately, this will break
all arches till they add in an libc/sysdeps/linux/<arch>/bits/syscalls.h
file. Sorry about there, there was no other way...

Patch from Shane Nay, who noticed that these were not properly labeling
functions as such, thereby hosing the shared lib loader.

Oops... forgot to remove rint.c from the makefile.

Remove Erik's broken implementation of rint(). Replace it by one "less broken".
Also correct rounding beharior of round() and add trunc(). Note that round()
and rint() currently don't check for infs and nans. I decided to wait on
that until the big cleanup.

Add in "HAVE_SHARED" so shared libs build or not as needed
-Erik

This was violating policy and using a kernel header file...
-Erik

This commit finishes adding support for the old m68k-coff toolchains by
working around a missing header file in the compiler shipped with the
uCsimm and uCdimm. This should make the folk in Toronto happy, since
now they can use the latest CVS version of uClibc.
-Erik

I went nuts and wrote a generic rint implementation. I think it is
correct per the man page and a little testing seems to show it works.

Update TODO file.

Add the in* and out* functions for i386. Note: the sys/io.h header for
glibc-2.2.2 actually defines static inline versions for i386, but only
provides prototypes for externs for the other archs I looked at. Since
uClibc shares this header amongst archs, I stashed the inline defs in
bits/io_i386.h and included it when __i386__ was defined. Better solutions
are most welcome, but it doesn't clutter sys/io.h too badly and now lilo
and the pcmcia tools build against uClibc on i386 without modification.

A few build updates

These are needed for powerpc to compile

Note missing struct _res in resolv.h
