PHP_OPERATOR_OPHANDLER_COUNT doesn't match with recent PHP 5's one.

operator.c in operator-0.4.1:
---
#define PHP_OPERATOR_OPHANDLER_COUNT ((25 * 151) + 1)
---

PHP 5.4 has more. It'll need conditional check like following:
---
#if (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION > 5)
# error "Operator overload support requires newer PHP_OPERATOR_OPHANDLER_COUNT"
#elif (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION == 5)
# define PHP_OPERATOR_OPHANDLER_COUNT				((25 * 164) + 1)
#elif (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION == 4)
# define PHP_OPERATOR_OPHANDLER_COUNT				((25 * 159) + 1)
#elif (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION == 3)
# define PHP_OPERATOR_OPHANDLER_COUNT				((25 * 154) + 1)
#else
# define PHP_OPERATOR_OPHANDLER_COUNT				((25 * 151) + 1)
#endif
---

I'll attach a patch for this problem.

Thanks
