`.global SYMBOL', `.globl SYMBOL'
=================================

   `.global' makes the symbol visible to `ld'.  If you define SYMBOL in
your partial program, its value is made available to other partial
programs that are linked with it.  Otherwise, SYMBOL will take its
attributes from a symbol of the same name from another partial program
it is linked with.

   Both spellings (`.globl' and `.global') are accepted, for
compatibility with other assemblers.
