Attachment 85248: remove prewin.h and postwin.h in sal unittests
https://bz.apache.org/ooo/attachment.cgi?id=85248&action=edit



--- Description ---
build process on windows is currently broken[1]
some unit tests in sal includes headers from tools which depends on sal
(circular dependencies)[2]
said headers are prewin.h and postwin.h which frame windows.h includes

I got no win build environment, but looking at the files I don't think they are
needed for the basic functionality sal (system abstraction layer) provides
would be happy to know if someone knows more about prewin and postwin

here a patch which removes the includes
if someone with a win build environment could test it or if no time let our
buildbot do the work. would be great

unit test framework for general usage in the build environment
