The IDL syntax that widl implements includes a subset of the C syntax,
however it is not practical to support the full C syntax (in
particular inline functions) and in this case widl doesn't like the
array initialiser. MIDL probably also suffers from similar limitations
and you'll see "#ifndef MIDL_PASS" in PSDK header files to work around
these sorts of issues. If you really have to treat commctrl.h as an
IDL file, you'll need to #ifdef out problem statements.
