Alright, appears that it is to be defined with the compiler (i.e. with
flag -D__STDC_LIMIT_MACROS).
Between the fact that making changes for MediaDefs.cpp and
STXTTranslator.cpp might cause problems with compiling for R5 and the
fact that it will surely work without the check (the way it is now), I
decided to leave out the check for now.
Since the constant macros and format macros have yet to be used, it is
safe to keep the checks in and any c++ code that needs them will need
to define __STDC_CONSTANT_MACROS or __STDC_FORMAT_MACROS with the -D
flag.
This patch adds some limit macros, adds the constant macros, and
removes the L suffix on INT32_MAX and UINT32_MAX. I currently left
WCHAR_MIN and WCHAR_MAX out for now (as well as the check for
__STDC_LIMIT_MACROS).
diff for stdint.h attached.
