Subject: 3270

Clean up the Globals section so that we can generate extern declarations
for all globals out using this command after we carve it out into
globals.cc:

  grep ';' globals.cc |perl -pwe 's/[=(].*/;/' |perl -pwe 's/^[^\/# ]/extern $&/' > globals.h

The first perl command strips out initializers. The second prepends
'extern'. This simplistic approach requires each global definition to
lie all on one line.
