The linker options:
`--stack RESERVE'
`--stack RESERVE,COMMIT'
 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
using
	-Wl,--stack,RESERVE
or	-Wl,--stack,"RESERVE,COMMIT" (may not work; there's a problem with
both ld and gcc using ',' as a delimiter)
