Hi Michael,
actually the SAL C API seems to work nicely - after Tor's remarks I re-
installed the MSVC-SDK and tried to link my MinGW-code against ist. However, 
the CPPU interface denies the linking - I observe undefined references to 
cppu::bootstrap(), cppu::BootstrapException::getMessage(), and 
cppu::defaultBootstrap_InitialComponentContext() :-( - probably a tribute to 
the decorations of the c++-function names
I tested the 3.5 MinGW snapshots quite a lot on Windows - the only problem I 
found so far was a "General error" message during reading or writing odt-
documents (to my naive opinion, this message seems to be a lie, since I could 
work as usual with the documents ignoring that "error"). On the other hand, 
when using doc-Files the error message does not show up. Thus, the 
functionality of the MinGW port seems to be sufficient for my needs.
Unfortunately I am not able to crosscompile the code - I always get stuck in 
the modules sal and libexttextcat, both with the message
i686-w64-mingw32-windres: unexpected version string length 68 != 32 + 8
I have no idea what this will tell me...
BTW - in case you need some (limited) help in doing the tests, let me know 
what I could do ;-)
