Hi,

I had to move #include <X11/Xlib.h> in GtkApp.cpp in order to compile in Windows with clang:

#include <CtrlCore/CtrlCore.h>


#ifdef GUI_GTK
#include <X11/Xlib.h>
#define CATCH_ERRORS 1

Additionally, compilation fails to missing include in MSBT22x64:

C:\upp-16323\upp.src\uppsrc\ide/clang/clang.h (5): fatal error C1083: Cannot open include file: 'clang-c/Index.h': No such file or directory

Best regards,

Tom
