configure flags

configure now regards additional CFLAGS and LDFLAGS set as environment variables.

CTRL handling

CTRL C and CTRL BREAK on console can be caught by setting a handler function with sapi_windows_set_ctrl_handler.

proc_open on Windows can be passed a "create_process_group" option. It is required if the child process is supposed to handle CTRL events.

OPcache

OPcache now supports an arbitrary number of separate caches per user via the INI directive opcache.cache_id. All processes with the same cache ID and user share an OPcache instance.

stat

The stat implementation has been refactored.

• An inode number is delivered and is based on the NTFS file index.
• The device number is now based on the volume serial number.

Note that both values are derived from the system and provided as-is on 64-bit systems. On 32-bit systems, these values might overflow the 32-bit integer in PHP, so they're fake.

libsqlite3

libsqlite3 is no longer compiled statically into php_sqlite3.dll and php_pdo_sqlite.dll, but rather available as libsqlite3.dll. Refer to the installation instructions for SQLite3 and PDO_SQLITE, respectively.
