-  Supported values for integers include the usual C notation
-  so decimal, octal (starting with 0) and hexadecimal (starting with 0x)
-  are supported. Examples:
-
-  "42"      ->  42
-  "042"     ->  34 (octal -> decimal)
-  "0x42"    ->  66 (hexa  -> decimal)
-
-  Warning: the conversion may overflow in various ways. Conversion is
-  totally outsourced to strtol(), see the associated man page for overflow
-  handling.

-  Credits: Thanks to A. Becker for suggesting strtol()
