Please describe the problem:
1. IPrintDialogCallback is already declared in CommDlg.h.
2. win32_status is declared at the middle of a block.
3. page_setup is doubly.

Steps to reproduce:
1. compile by old compiler

Actual results:

Expected results:
1. The 2nd declaration in gtkprintoperation-win32.c have to be disable.
2. The declaration have to be moved to top of block.
3. Delete page_setup.

Does this happen every time?
