/*
|
|
* The C99 standard header <stdint.h> exposes typedefs for common fixed-width
|
|
* integer types. It would be feasible to simply #include <stdint.h>, but
|
|
* MSVC++ versions prior to 2010 don't provide <stdint.h>. We could solve this
|
|
* by reimplementing <stdint.h> for MSVC++ 2008 and earlier. But then we reach
|
|
* a second problem: our custom <stdint.h> might conflict with a <stdint.h>
|
|
* defined by an embedder already looking to work around the MSVC++ <stdint.h>
|
|
* absence.
|
|
*
|
|
* We address these issues in this manner:
|
|
*
|
|
* 1. If the preprocessor macro MOZ_CUSTOM_STDINT_H is defined to a path to a
|
|
* custom <stdint.h> implementation, we will #include it. Embedders using
|
|
* a custom <stdint.h> must define this macro to an implementation that
|
|
* will work with their embedding.
|
|
* 2. Otherwise, if we are compiling with a an MSVC++ version without
|
|
* <stdint.h>, #include our custom <stdint.h> reimplementation.
|
|
* 3. Otherwise, #include the standard <stdint.h> provided by the compiler.
