Subject: [PATCH] Corrected an error in "extresist" that can output an
 incorrect number of terminals for devices that don't have the usual gate/
 source/drain terminals (e.g., diodes, resistors, capacitors) when writing the
 devices with re-mapped terminals into the .res.ext file.  Also:  Changed the
 size of the word containing the name refcount for "equiv" statements, since
 an accidental shorting of pins can cause a large number of "equiv" statements
 in a .ext file, causing an overrun of the previously 1-byte refcount (this
 probably does not make the structure any longer, since it likely has to fit
 to a word boundary).
