Fortran lint/intercompilation analyzer under Ultrix?

[CORBATO at cc.utah.edu]

Does anyone know of a Fortran precompilation analyzer for `generic' Fortran
(i.e., DEC or MIPS) running under Ultrix?  Intercompilation analysis of
common blocks and subroutine/function variable would be a desired feature as 
well.
