Whatever is the default on Cygwin; I never used '--stack' to change it 
until yesterday.  'ulimit -s' returns 2025, so I guess that means the 
default stack is only 2MB.  I've asked on the Cygwin list whether this 
should be increased.

OK.

The reason Ryan had to increase it is that he was building from my 
patched sources for the Cygwin distribution.  I deliberately reduce the 
static heap for that build, because building from the source tarball 
doesn't require as big a static heap as a bootstrap.  I bootstrapped the 
trunk yesterday with --enable-checking=all and the static heap was big 
enough for that (but just barely).

Thanks.
