1.5 Gig is about the most it's possible to get under 'doze. The address
space of the processor is 4gig, the upper 2 gig (addr >= 0x80000000) belong to
the kernel, the lower 2 gig belong to user-land. Take away 512k at the top of
that for the space where the dll's load (0x600000000 - 0x7fffffff), and what
you're left with is what you get.
As to the FAQ entry, it really needs a little alteration. Ping JDF!
It should make clear that those parameters are in bytes. The example of a
4k stack and 1k heap is a bit unrealistic and it might be more productive to
show people how to make exes with /big/ stacks, since that's the problem
people usually run into. How about something a bit more like

21.
How can I adjust the heap/stack size of an application?
If you need to change the maximum amount of memory available to Cygwin, see
http://cygwin.com/cygwin-ug-net/setup-maxmem.html. Otherwise, just pass the
desired heap/stack size in bytes as linker arguments to gcc. To create foo.exe
with a heap size of 200MB and a stack size of 8MB, you would invoke gcc as:
gcc -Wl,--heap,200000000,--stack,8000000 -o foo foo.c
