The feature branch is http://git.php.net/?p=php-src.git;a=shortlog;h=refs/heads/str_size_and_int64

Currently int64 support is disabled by default, size_t support is enabled by default

• to build with size_t and int64 support use --enable-zint64 , size_t is enabled by default
• to build without size_t and int64 support, use --enable-zstrlen , int64 is disabled by default

• Zend/zend_types.h
• Zend/zend_int.h
• Zend/zend_stream.h
• main/php_stream.h

• zend_str_size has to be used for all the string sizes
• zend_int_t, zend_uint_t are to be used instead of long and ulong
• zend_off_t should be used instead of off_t
• zend_stat_t, php_int_t should be used instead of “struct stat”
• zend_fstat(), zend_stat_fn() macros are suitable to handle the *_stat_t types

BE AWARE OF WHAT size_t IS, READ SOME DOC BEFORE STARTING TO AVOID TRIVIAL MISTAKES

• Z_STRSIZE is the replacement for Z_STRLEN
• ZEND_INT_MAX is the replacement for LONG_MAX, as well ZEND_UINT_MAX, ZEND_SIZE_MAX for the corresponding old macros

• “S” to accept string argument, the length has to be declared as zend_str_size, to replace the string length related variables with size_t, the appropriate macros from Zend/zend_types.h should be used (zend_str_size_int, zend_str_size_long, etc.)
• “P” is the replacement for “p”
• “i” to accept integer argument, the internal var has to be declared as php_int_t (inside PHP) or zend_int_t (inside Zend)
• “I” to accept integer argument with range check, the internal var has to be declared as php_int_t (inside PHP) or zend_int_t (inside Zen

Initial work is done by ircmaxell, with that it compiles on linux and windows.
