Add an 'XLFLAGS' make variable to Makefile.vc, permitting user-

supplied extra link flags. This makes it reasonably convenient to
compile for Visual Studio debugging: just build using

  nmake /f Makefile.vc XFLAGS="/Zi /Od" XLFLAGS="/debug"

then load the resulting executable into Visual Studio (using 'Open
Project' rather than 'Open File') and the debugger should be able to
access the source.
