 +  e. New data types
 +     
 +     String length
 +
 + String lengths do no more depend on the firm 'int' datatype. The replacement
 + is a platform dependent size_t datatype. The string length in zval is no more
 + int but php_size_t.
 +
 + String length is defined as zend_size_t inside Zend and aliased as php_size_t
 + anywhere else. The inclusion of php.h is necessary.
 +
 +     Integer types
 +
 + Integers do no more depend on the firm 'long' type. Instead a platform
 + dependent integer type is used. That datatype is defined dynamically to
 + guarantee the consistent 64 bit support. The zval field representing user
 + land integer it bound to php_int_t.
 +
 + Signed integer is defined as zend_int_t, unsigned integer as zend_uint_t
 + inside Zend. Both are aliased as php_int_t and php_uint_t anywhere else,
 + respectively. The inclusion of php.h is necessary.
 +
 +     Other datatypes
 +
 + zend_off_t  - portable off_t analogue
 + zend_stat_t - portable 'struct stat' analogue
 +
 + These datatypes are declared to be portable across platforms. Thus, direct
 + usage of the functions like fseek, stat, etc. as well as direct usage of
 + off_t and struct stat is strongly not recommended. Instead the portable
 + macros should be used.
 +
 + zend_fseek - portable fseek equivalent
 + zend_ftell - portable ftell equivalent
 + zend_lseek - portable lseek equivalent
 + zend_fstat - portable fstat equivalent
 + zend_stat  - portable stat equivalent
