What is the signature of the MessageBoxA() function in C code?
There may be two issues:
1) we currently marshal strings as utf8 char*. MessageBoxA() for all I
know may want UTF-16 (though I guess the 'A' is for ASCII?).
2) The call convention: we call the P/Invoke function with th cdecl call
convention by default. It may be that MessageBoxA() uses another

You could try to run the code with the ms runtime and check if it works
