[Gcl-devel] STABLE BRANCH PATCH - sbrk() configure.in

PS - Here is a patch for the Stable branch which side steps the test on 
Windows.

I suppose we should really test for the existence of sbrk first on the 
assumption that one day we might have other platforms without sbrk and 
then based on that result, do your randomised sbrk tests.

I can check this in sometime over the next day or two if you are happy 
with it.

Cheers
