* removed dependences to unsupported by new MSVC header files
most of this modifications can be enabled also for standard Win32
builds
* harbour/source/common/hbwince.c
* do not create dummy LocalLock() and LocalUnlock() function in MSVC
WinCE builds
* harbour/source/rtl/gtwin/gtwin.c
+ added HB_WINCE_USE_POCKET_CONSOLE macro which enable
console support in WINCE builds (macro suggested by Marek Paliwoda)
* harbour/source/rtl/gtwvt/gtwvt.h
* harbour/source/rtl/gtwvt/gtwvt.c
* changed default window and font size on WinCE to values suggested
by Marek Paliwoda
Marek if you have a while please make test with MSVC WinCE/PocketPC
builds and current SVN code.
