This is probably the last bit needed to make gfortran entirely  
competitive in the Fortran 95 compiler market.  Congratulations!

Out of curiousity, why didn't you use alloca instead of doing all this  
bookkeeping?  Maybe because you would have needed bookkeeping anyway  
for the case where the allocatable component would have been >  
-fmax-stack-var-size?  Or is there a simpler reason?
