If you port C code them maybe you want to write:


__gshared long gi;

 __gshared long gi;

It is doesn't matter, this code doesn't have sence in D, enums are calculated
in compile time, but preprocessor just pastes code in C.

When porting C code, it is very difficult to find such error due dmd just
crashes without any message.
