Fix the MSVC build on MS-Windows.

 output.c (vsnprintf) [_MSC_VER]: Define, instead of defining
 snprintf, which isn't used.  Reported by Christian Boos
 <cboos@edgewall.org>.
 NMakefile.template (OBJS): Add load.obj and posixfcn.obj.
 ($(OUTDIR)/pathstuff.obj): New dependency.
 Suggested by Christian Boos <cboos@edgewall.org>.
