This is just a simple request for a header or a class that allows access to operational parameters like the bit width and max/min values of integral types, etc.

If there's something a rusty C programmer with a few months of php under his belt could do to help on it, let me know.

already introduced in 4.3.12, PHP 5.0.5+ :
PHP_INT_MAX (LONG_MAX from limits.h)
PHP_INT_SIZE (4 on 32 bit, 8 on 64 bit (sizeof(long)))
constants 

The reason for using "long" as type is that internally the integers (in PHP sense) are stored by PHP as long-s.
