[CAGE] Fixed a few warnings and a NCI example on Windows using MSVS

Reported by: ujwal Owned by: cotto
Priority: normal Milestone:
Component: configure Version: trunk
Severity: medium Keywords:
Cc: Language:
Patch status: new Platform: win32

Description

Fixed warnings like unused variables, unreachable code in core.ops
config/gen/platform/win32/exec.c
config/gen/platform/win32/stat.c
include/parrot/encoding.h
src/embed.c
src/oo.c
src/ops/core.ops
src/packfile.c
src/spf_render.c
src/string/encoding.c
src/string/encoding/fixed_8.c
src/thread.c

also Fixed a NCI example
examples/nci/PQt.C
examples/nci/PQt.cpp
examples/nci/QtHelloWorld.pasm
examples/nci/QtHelloWorld.pir

this is a good way to get comfortable with code base :)

I have more msvc warnings. Two look important:

src/thread.c(503): Parrot_Interp  interp = (Parrot_Interp)VTABLE_get_pointer(interp, self); 
'interp' used without having been initialized

and here we miss an explicit double => long cast:
