This flag prevents the compiler from merging multiple tenative global
variable declarations (e.g. 'int i;' without an assignment) into a
single copy later. In the default (-fcommon) mode, this allows multiple
definitions of an uninitialized global variable to be linked into a
single program without any warnings.
