First, C does not have anything called a "global scope". The snipped
you have shown, if it were compiled, has the definition of an unnamed
structure type, the definition of an alias for that type, and the
definition of an object of this structure type with internal linkage,
all at "file scope", which is the largest scope that C has.

Secondly, even if there is no other definition of that structure type
in other translation units, there still could be another identifier
named "a" with external linkage in other translation units, which
could cause a problem if the static keyword is removed from the object
definition, giving this identifier "a" external linkage.
