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.
