c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk# extern names are safe from being mistaken as names from other
c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk# libraries, you better use a mapfile, or use a unique naming
c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk# convention on all your extern symbols.
