+ 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. */
