compiler warning: double definition of macro JSON_INTERNAL_CATCH

[RalfBielig]

• version 3.2.0

#define JSON_CATCH_USER(exception) if(false)
#include "nlohmann/json.hpp"

single_include/nlohmann/json.hpp:211:0: warning: "JSON_INTERNAL_CATCH" redefined
single_include/nlohmann/json.hpp:198:0: first definition of macro "JSON_INTERNAL_CATCH"

[nlohmann]

This was introduced by #1187.

@simnalamburt Could you have a look at this please?

[nlohmann]

I can confirm the warning. Minimal compilable program:

#define JSON_TRY_USER if(true)
#define JSON_CATCH_USER(exception) if(false)
#include "single_include/nlohmann/json.hpp"

int main()
{}

Oops I catched the mistake. I'll send a follow-up PR
