25 * Note - this handles reading debug information for 32 bit applications
26 * that run under Windows-NT for example. I doubt that this would work well
27 * for 16 bit applications, but I don't think it really matters since the
28 * file format is different, and we should never get in here in such cases.
31 * Get 16 bit CV stuff working.
32 * Add symbol size to internal symbol table.
