[cairo] Errors building cairomm-1.7.0 on Windows, MinGW/MSys gcc 4.3.0 20080502 alpha

[Paul Goins]

I already know, I'm using an alpha gcc, I'm asking for trouble.  But
I've looked at the cairomm code a little and it looks like at least some
of these build errors are legitimate.

Here's a pastebin of the error as part of running "make -k":

The errors seem centralized in cairomm/win32_surface.{h,cc}.  I looked
at the first error, about ~Cairo::Win32Surface being declared (in error)
a member of Cairo::Win32PrintingSurface, and unless I'm missing
something, Win32PrintingSurface is not a child of Win32Surface according
to the code.  I haven't looked at the rest though.

I'm happy for any help or workarounds which may be available.
