[FLASH-BUGS] Flash - Fortran90 compiler compatibility on Tru64

[Colin McNally]

Hi,
  I have had to hack out some of the FORTRAN common blocks in PARAMESH 
that were used by the dataBase module into common blocks to make Compaq 
Tru64 Fortran compile FLASH (intgrs, floats,tree,solution_cc). It is 
possible that my modifications have messed something up.  
    The issue is that when a common block is defined by Paramesh and is 
used in a dBase module and then a name in the common block is in the 
ONLY specification of a USE statement the compag compiler, for example goes:

f95 -cpp  -c -fast  -r8 -i4 -I/usr/mpi/include  -DN_DIM=2 
-DMAXBLOCKS=1000  flash.F90
f90: Error: flash.F90, line 74: Conflicting attributes or multiple 
declaration of name.   [NSTEP]
  do nstep = nbegin, nbegin+nend
-----^
f90: Error: flash.F90, line 74: An INTEGER or REAL data type is required 
in this context.   [NSTEP]
  do nstep = nbegin, nbegin+nend
-----^
f90: Error: flash.F90, line 79: Conflicting attributes or multiple 
declaration of name.   [NSTEP]
     if (MyPE == MasterPE) call tstamp_logfile (nstep, time, dt)
------------------------------------------------^
f90: Error: flash.F90, line 92: Conflicting attributes or multiple 
declaration of name.   [NSTEP]
     call output(time, dt, nstep, nbegin) ! Output if needed
---------------------------^
f90: Error: flash.F90, line 106: Conflicting attributes or multiple 
declaration of name.   [NSTEP]
  call end_flash (nstep-nbegin+1)
------------------^
f90: Error: flash.F90, line 40: Name in only-list does not exist.   [NSTEP]
  use dBaseDeclarations, ONLY: nstep
-------------------------------^
gmake: *** [flash.o] Error 1


This is the sod test.  Striaght out of the box FLASH2.1 and 2.0. Is 
there a recommended strategy for fixing this that's less painful then 
hacking out all the affected common block refrences and hacking the new 
module refrences in every new release of FLASH?

Included find a Makefile.h for osf1t5. To recreate the problem drop it 
into the approprite directory and do ./setup sod -auto ; gmake      

This issue was seen with:
Compaq Fortran V5.5-1877
Compaq Fortran Compiler V5.5-1877-48BBF
