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) -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
