    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.
