/*
* Types:
* JSInt<N>, JSUint<N> (for <N> = 8, 16, 32, and 64)
* JSIntPtr, JSUIntPtr
*
* JSInt<N> and JSUint<N> are signed and unsigned types known to be
* <N> bits long. Note that neither JSInt8 nor JSUInt8 is necessarily
* equivalent to a plain "char".
*
* JSIntPtr and JSUintPtr are signed and unsigned types capable of
* holding an object pointer.
*
* Use these types in public SpiderMonkey header files, not the
* corresponding types from the C standard <stdint.h> header. Windows
* doesn't support <stdint.h>, and Microsoft says it has no plans to
* do so in the future; this means that projects that embed
* SpiderMonkey often take matters into their own hands and define the
* standard types themselves. If we define them in our public
* headers, our definitions may conflict with embedders' (see bug
* 479258). The JS* types are in our namespace, and can be used
* without troubling anyone.
*
* Internal SpiderMonkey code wishing to use the type names ISO C
* defines in the standard header <stdint.h> can #include
* "jsstdint.h", which provides those types regardless of whether
* <stdint.h> itself is available.
