You may be able to eliminate the #include order problems by changing your build process to define the __STDC_LIMIT_MACROS symbol on the compiler command line instead:

cxx -D__STDC_LIMIT_MACROS ...

Of course, you would still have trouble if a header #undefs this symbol.

Also, the authors of the standard library implementation that you are using might not have intended for users to set that particular symbol; there might be a compiler flag or a different symbol that users are intended to use to enable C99 types in C++.
