When the macro ${../if/declare-global-symbol:/name} appears at file scope,
and argument ${../if/declare-global-symbol:/params[0]/name} after undergoing
C pre-processor substitutions results in a valid C identifier name,
and this identifier name is not yet defined at file scope,
the macro ${../if/declare-global-symbol:/name} shall apply all possible C
pre-processor substitutions to its argument value
before it results in code which declares a global symbol
with the respective name.
