__WXMSW__ is not defined when compiling wxBase, so the tests which were meant to prevent using Unix event loop classes under Cygwin (under which both __UNIX__ and __WINDOWS__, but not __WXMSW__, are defined) failed, breaking compilation of all wxEventLoop-related code in wxBase in Cygwin builds. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_3_0_BRANCH@76516 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
