WIDL 'import' question

[Nikolay Sivov]

Hi, I've a small question on using 'import' in .idl. Sorry if it's too 
dummy, it's my first try to use widl.
Trying to get commoncontrols.idl port compile on Wine I've got the 
following problems -
this file contains struct definitions already defined in commctrl.h.

Adding

    import "commctrl.h"

and removing after that all conflict definitions from commoncontrols.idl 
caused for me

../tools/widl/widl -I. -I. -I../include -I../include    -h -H 
commoncontrols.h commoncontrols.idl
./prsht.h:39: error: syntax error, unexpected '{'
make[1]: *** [commoncontrols.h] Error 1
make[1]: Leaving directory `/home/mrlarch/wine/include'
make: *** [include] Error 2

showing that prsht.h isn't processed properly here

39    static const WCHAR WC_PROPSHEETW[] = { 'S','y','s',
40      'P','r','o','p','e','r','t','y','S','h','e','e','t',0 };

How could I get over that?
