The #error is unfortunate. It all comes about because the C standards
committee tried to define C++ and they got it wrong. Then this wrong
concept was burned into stdint.h, for poor project folks to deal with.
From the header itself:
// Note that this header's correct operation depends on
// being defined. We would define it here, but in order to prevent
// happening when system headers or C++ STL headers include stdint.h
// we define it here, we define it on the g++ command line (in

So, for now, it looks like you have to define the on the command
This code is bogus however, working stdint.h files don't need this
defined and checking it like this is wrong.
