_X_ void vshMakeAbsolutePath(const char *orig, char *new)
{
  // Desc: Turns a filename, specified by 'orig', into an absolute pathname 'new'.  This basically just amounts to prepending the name of the current directory (plus a '/') to the supplied name.  'new' must be a buffer large enough to hold the entire filename.

  // Use shared code
  #include "../shared/abspath.c"
