% gcc -v --help |& grep stack
-fstack-limit-register=<register> Trap if the stack goes past <register>
-fstack-limit-symbol=<name> Trap if the stack goes past symbol <name>
-fstack-check Insert stack checking code into the program
-fomit-frame-pointer When possible do not generate stack frames
-fdefer-pop Defer popping functions args from stack until later
-fstack-checking Enable stack checking (same as `{$S+}')
-fno-stack-checking Disable stack checking (same as `{$S-} (default)')
-mstack-arg-probe Enable stack probing
-mpreferred-stack-boundar Attempt to keep stack aligned to this power of 2
--stack <size> Set size of the initial stack

However, this may actually also be a sign that you need to run rebaseall.
See /usr/share/doc/Cygwin/rebase*.README .
