Please stop closing this. It has garnered quite a few views and is, apparently, helpful to others. Yes, you should have read the man page more carefully but that happens to the best of us. – terdon May 6 '14 at 10:25

It's -f as "flag" and no as "no stack limit"

The flag description was a bit confusing: Generate code to ensure that the stack does not grow beyond a certain value, either the value of a register or the address of a symbol. (...) – ΔλЛ May 5 '14 at 21:45
@REACHUS: the GCC man page usually uses the same paragraph for -fdo-foo and -fno-do-foo. What's documented is the -fdo-foo in that case, you're supposed to deduce what the opposite would be. – Mat May 6 '14 at 5:48
