What command line parameter do I need with Gnat 3.15p to increase the
main program's stack size?

-largs -Wl,--stack=0x1000000

see the GNAT User's Guide: 5.3 Setting Stack Size from gnatlink

gnatmake big -largs -Wl,--stack=0x1000000
works for a parameter of 4022 but gives:
raised STORAGE ERROR : EXCEPTION_STACK_OVERFLOW
with a parameter >= 4023, while either of
gnatmake big -largs -Wl,--stack=0x2000000
gnatmake big -largs -Wl,--stack=0x8000000
work for 4023 .. 4025 but 4026 again gives:
raised STORAGE_ERROR : big.adb:4 object too large

For what's it worth, I just installed Gnat 2006 for Windows, and
converted your test procedure. By using the -Xlinker
--stack=0x10000000 on it, I was able to successfully run big 64000 on
XP (technically, Tablet PC).

So either you need to use the -Xlinker variant, or there is a
limitation in the 3.15 version of the compiler. Or you are using an
older version of Windows that doesn't support this.
