stdcall is a Microsoft thing. What are these C compiler standards you are
talking about? AFAIK there are no standards for stdcall, only conventions.

In a time before Cygwin and MinGW GCC did not know about stdcall.
As GCC already had some other __attribute__((somethings)) they implemented
stdcall as another function attribute instead of adding a new keyword.
To get the Microsoft keyword #define __stdcall __attribute__((stdcall))

__stdcall has two underscores because the C standard (the real standard)
says that all names that begin with two underscores are reserved, meaning
you're on your own if there are name clashes when your code introduces a
variable, function, or macro with the same name.
