- Made macros of couple of tests previously littering configure.in
(e.g. PHP_PROG_AWK, PHP_PROG_LEX, PHP_PROG_BISON..)
- Moved all PHP_SUBST() calls into their respective macros.
(no point adding empty entries in Makefile if macro is not used)
* all internal use of sprintf, snprintf and the like will always
use the . as thousands seperator (if php.h is included only!).
* echo, printf() and sprintf() always render locale-aware
* added the %F modifier for non-locale aware rendering for floats
/usr/lib64 rather than /usr/lib.
* configure.in: Add --with-libdir flag; define PHP_LIBDIR.
* acinclude.m4 (PHP_REMOVE_USR_LIB, PHP_RUNPATH_SWITCH,
PHP_ADD_LIBPATH): Check for /usr/$PHP_LIBDIR rather than /usr/lib.
(PHP_SETUP_OPENSSL, PHP_SETUP_ICONV): Use /path/to/$PHP_LIBDIR in
place of /path/to/lib.
We avoid the problem by using poll(2).
On systems without poll(2) (older bsd-ish systems, and win32), we emulate
poll(2) using select(2) and check for valid descriptors before attempting
to access them via the descriptor sets.
If an out-of-range descriptor is detected, an E_WARNING is raised suggesting
that PHP should be recompiled with a larger FD_SETSIZE (and also with a
suggested value).
Most uses of select(2) in the source are to poll a single descriptor, so
a couple of handy wrapper functions have been added to make this easier.
A configure option --enable-fd-setsize has been added to both the unix and
win32 builds; on unix we default to 16384 and on windows we default to 256.
Windows FD_SETSIZE imposes a limit on the maximum number of descriptors that
can be select()ed at once, whereas the unix FD_SETSIZE limit is based on the
highest numbered descriptor; 256 should be plenty for PHP scripts under windows
(the default OS setting is 64).
The win32 specific parts are untested; will do that now.
