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