#1109 SciTE 64-bit build bugs
Recently I tried to build 64-bit versions of SciTE, although I don't know if this is currently supported at all.
Visual Studio 2010 builds SciTE 2.24 successfully in 64-bit mode. There are many warnings regarding type conversions, but the resulting binary seems to work - with two exceptions:
1. Menu localisation does not work, this is fixed with the attached patch scite_x64_1.diff.
2. Lua scripts freeze SciTE. I'm not sure if it's the correct fix, but the attached patch scite_x64_2.diff seems to work.
Building SciTE 2.24 with MinGW64 doesn't work. There are type conversion errors in DirectorExtension.cxx and LuaExtension.cxx. I was able to convert the errors to warnings by changing the type casts, but this was by trial and error.

I commonly build SciTE as 64-bit on Linux and 32-bit on Windows. Others occasionally send in patches for 64-bit Windows.
The menu localisation patch is OK as 64-bit use is now more common than NT 4.
For iface_function_helper in LuaExtension, I expect the patch is just covering up that the params variable only contains 32-bit values and needs to be 64-bit (probably sptr_t) on Win64, particularly for the iface_string and needStringResult cases where params[1] is a pointer to string buffer.
OK, I've changed the patch for LuaExtension.cxx (see scite_x64_3.diff). The type of the params variable is now sptr_t.
LuaExtension.cxx with this patch applied compiles without warnings with MinGW32, MinGW64, VS 2010 (32 + 64 bit). Lua scripts work with all builds.
Committed.
