* configure.ac: Only pass -c to ranlib for darwin9 and earlier.
* configure: Regenerate.
const in parameter list.

spinlock on sversion and remove other spinlock-like things. Remove reference
to user_shared since it is now implicit. Refer to spinlock version of

here under spinlock control. Move unneeded non-shared_info initialization out
of this function.
(memory_init): Remove call to init_installation_root. Call heap_init and
get_session_parent_dir here.
* libm/common/s_rint.c: Fix error when integral part had 18 bits and
fraction had bits set beyond first radix bit. Also, make 2-part
adjustment consistent with 1-part adjustment when adjusting fractional
bits.
* libm/common/sf_rint.c: Make fractional-bit adjustment consistent
with s_rint.c by setting 0b.01 instead of 0b.001.
* libc/stdlib/getenv.c: Delete "char *_findenv_r ();", as is not a
proper prototype, and is properly prototyped in stdlib.h, anyway.
* libc/stdlib/getenv_r.c: Ditto.
* libc/search/hash.c: Add _DEFUN to __hash_open() declaration; add
#define __DBINTERFACE_PRIVATE to activate prototypes from db_local.h.

Remove #define INFINITY (redefines from math.h); remove #define __isnanf
and #define __isinff isinff.
blessed_executable_suffixes to static.

for appending a .exe suffix and (yikes!) document them.
* libc/include/sys/features.h: Add POSIX.1-permitted definition of
_POSIX_C_SOURCE if not already defined and _XOPEN_SOURCE has an
appropriate value. Specifically, check for POSIX.1-2008 & 2001 values.

includes get the new check added to it.

implementations.
* libc/xdr/Makefile.am: Eliminate automake warning.

_cygtls.
* cygtls.cc (_cygtls::init_exception_handler): Just assume that we're always
using the standard exception handler.
(_cygtls::init_thread): Reflect loss of argument to init_exception_handler.
