g77, on most machines, puts many variables and arrays on the stack
where possible, and can be configured (by changing
`FFECOM_sizeMAXSTACKITEM' in `gcc/f/com.c') to force
smaller-sized entities into static storage (saving
on stack space) or permit larger-sized entities to be put on the
stack (which can improve run-time performance, as it presents
more opportunities for the GBE to optimize the generated code).
Note: Putting more variables and arrays on the stack might cause problems due to system-dependent limits on stack size. Also, the value of `FFECOM_sizeMAXSTACKITEM' has no effect on automatic variables and arrays. See section Bugs Not In GNU Fortran, for more information.
