* contrib/hbexpat/3rd/expat/loadlibr.c
! define _UNICODE macro when UNICODE is also defined - it should be fixed
in EXPAT core code. It fixes Windows builds.
* contrib/hbexpat/3rd/expat/xmlparse.c
! restored fix for WINCE builds
* contrib/hbtip/client.prg
! restored #undef __HBEXTREQ__ before #include "hbssl.hbx".

functions.
