The linker options:

`--stack RESERVE'
     Specify the number of bytes of memory to reserve (and optionally
     commit) to be used as stack for this program.  The default is 2Mb
     reserved, 4K committed.  [This option is specific to the i386 PE
     targeted port of the linker]

Obviously, the OP would need to pass these 'thru' the gfortran compiler
or	-Wl,--stack,"RESERVE,COMMIT" (may not work; there's a problem with
both ld and gcc using ',' as a delimiter)
