gfortran compiles
--------------------
SUBROUTINE OPT1 (IB)
IMPLICIT REAL*8 (A-H,O-Z)
COMMON /INTNEW/ VL,EPS,BEGIN,STEP
END
SUBROUTINE OPT0(E0,H0,P0,NUMB,X,Y)

------------------
without any warning (as does ifort). However, you should either warn or give an
error if two commons don't match.
NAGWare compiler fails with an ERROR:
------------------
Error: test5.f90: Inconsistent definitions of COMMON block INTNEW in
program-units OPT1 and OPT0
------------------
g95 compiler (with only "-c" and not -Wall) compiles, but spits out the
warning:
