Fork

Work from Stefan Allius which allows superH to use the common
method for building crti.o and crtn.o

Based on work by Stefan Allius, arrange for early initialization of
pthread stuff. Also, don't bother building libthread_db unless we
are debugging.
-Erik

Open a lib that is not so closely coupled with gdb

Be prepared to call __pthread_initialize_minimal

(CSRC): Make contents source files, not object files.

(CSRC): Add `memalign.c'.

Initial checkin.

(realloc): Follow new arg conventions of MALLOC_SET_SIZE.

(malloc): Use MALLOC_SETUP.

(MALLOC_SETUP): New macro.
(MALLOC_SET_SIZE): Take the base-address of the block, not the user-address.
(MALLOC_ADDR): Macro removed.

Directly use kernel types for uid_t, gid_t, and dev_t to avoid the
need to translate these entities...
-Erik

Yet more rework to make __getgrent and the functions that use it
reentrant...
-Erik

Fix broken locking so that at least the Python 2.2.1 grp test doesn't
lock up. This really needs to be looked at, as I don't think this
needs to be reentrant. In any case, several routines call the
__getgrent internal routine and it uses static vars for data. If this
stuff is really supposed to be threadsafe, then __getgrent probably
needs fixing.

Remove recursive lock/unlock for a non-recursive mutex.

Fixed __read_etc_hosts_r to return alias list and modified buffer
allocation accordingly. This fixes the segfault in the Python 2.2.1
socket test.

Fix two problems with printf that showed up in the python 2.2.1 tests;
One involving %o and one involving %f.

Disable macro implementations. Somehow I missed the following from the
ANSI/ISO C99 std...

A library macro that masks a function declaration expands to an
expression that evaluates each of its arguments once (and only once).
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Arguments that have side effects evaluate the same way whether the
expression executes the macro expansion or calls the function. Macros
for the functions getc and putc are explicit exceptions to this rule.
Their stream arguments can be evaluated more than once. Avoid argument
expressions that have side effects with these macros.

This will be reworked before the next release. And yes, I feel stupid.

Cleanup exit a bit, from Ronald Wahl

whitespace

Remove __res_state function.

Make INCLUDE_FULL_RPC default to !HAVE_SHARED.

Demonstrate that dlopen() RTLD_NOW is currently broken.
-Erik

Remove thread-specific stuff entirely.

(_res): Define as a macro if __UCLIBC_HAS_THREADS__ is defined,
regardless of _LIBC.

(h_errno): Only define as a macro if __UCLIBC_HAS_THREADS__ is defined.
(__set_h_errno): Just assign to `h_errno' (which will be expanded to the
thread-friendly version when appropriate).

(errno): Only define as a macro if __UCLIBC_HAS_THREADS__ is defined.
(__set_errno): Just assign to `errno' (which will be expanded to the
thread-friendly version when appropriate).

Replace all instances of _LIBC_REENTRANT with __UCLIBC_HAS_THREADS__
-Erik

Remove h8300 special case

(headers): Remove special case for v850, now that the general case
works correctly for non-MMU systems without a `nommu' suffix.
Fixup indentation a bit.

Fix erroneous grouping.
