1574 * C99 typedefs are quite good but not always available, and we want to avoid
1575 * forcibly redefining the C99 typedefs. So, there are Duktape wrappers for
1576 * all C99 typedefs and Duktape code should only use these typedefs. Type
1577 * detection when C99 is not supported is best effort and may end up detecting
1578 * some types incorrectly.
1579 *
1580 * Pointer sizes are a portability problem: pointers to different types may
1581 * have a different size and function pointers are very difficult to manage
1582 * portably.
1583 *
1584 * http://en.wikipedia.org/wiki/C_data_types#Fixed-width_integer_types
1585 *
1586 * Note: there's an interesting corner case when trying to define minimum
1587 * signed integer value constants which leads to the current workaround of
1588 * defining e.g. -0x80000000 as (-0x7fffffffL - 1L). See doc/code-issues.txt
1589 * for a longer discussion.
1590 *
1591 * Note: avoid typecasts and computations in macro integer constants as they
1592 * can then no longer be used in macro relational expressions (such as
1593 * #if DUK_SIZE_MAX < 0xffffffffUL). There is internal code which relies on
1594 * being able to compare DUK_SIZE_MAX against a limit.
