## Old FORTRAN that mixes use of COMMON blocks and BLOCK DATA requires that we
## search through archives for non-tentative definitions (from the BLOCK DATA)
## to replace the tentative definitions (from the COMMON block(s)).
## Ensure we have used the initialized definition of 'block' instead of a
## common definition.
