minwindef.h defines FARPROC without (void) argument list, so if it is already included when volk.c is compiled via VOLK_IMPLEMENTATION, gcc will emit an error (MSVC handles this mismatch fine). Unfortunately, simply removing (void) results in a warning with Wstrict-prototypes even when volk.c is compiled as standalone. We could disable the warning with a pragma but for now we could simply reuse FARPROC definition from minwindef.h if it's already included.
