Fixes to syborg-graphicswrapper.vcproj
These changes allow syborg-graphicswrapper to link against the hostthreadadapter and khronosapiwrapper libraries built by the graphics.simulator component.
The .vcproj file uses relative paths, which requires that the following three packages are laid out as follows:
os/
graphics
adapt/
graphics.simulator
qemu
/* Sigcheck is similar to intrcheck() but sets an exception when an
interrupt occurs. It can't be in the intrcheck.c file since that
file (and the whole directory it is in) doesn't know about objects
or exceptions. It can't be in errors.c because it can be
overridden (at link time) by a more powerful version implemented in
signalmodule.c. */
