win32ole: separate global variable declarations and definitions
https://gcc.gnu.org/gcc-10/changes.html#c
> * GCC now defaults to `-fno-common`. As a result, global
> variable accesses are more efficient on various targets. In
> C, global variables with multiple tentative definitions now
> result in linker errors. With `-fcommon` such definitions are
> silently merged during linking.
