+     static variable.  For static variables within a function, this
+     globalization prefix is followed by the function name (nested
+     static variables within a function are supposed to generate a
+     warning message, and are left alone).  The procedure is
+     documented in the Stabs Interface Manual, which is distrubuted
+     with the compilers, although version 4.0 of the manual seems to
+     be incorrect in some places, at least for SPARC.  The
+     globalization prefix is encoded into an N_OPT stab, with the form
+     "G=<prefix>".  The globalization prefix always seems to start
+     with a dollar sign '$'; a dot '.' is used as a seperator.  So we
+     simply strip everything up until the last dot.  */
