## 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.
