Fortran : ICE in build_field PR95614
Local identifiers can not be the same as a module name. Original
patch by Steve Kargl resulted in name clashes between common block
names and local identifiers. A local identifier can be the same as
a global identier if that identifier represents a common. The patch
was modified to allow global identifiers that represent a common
block.
