Works on Cygwin, so pushed. During patch development I tested various
multi-dotted version numbers with various difficulties of the
4.82.620 vs 4.82.2000, 2.82 vs 10.7 and 4.10 vs 4.100 kind, as well
as some simple ones of the 5 vs 8 and 4.3 vs 4.8 variety.

*checks some more*

Hmmm, just checked 1.4.4a vs 1.4-p3a, and the new sort thinks 1.4-p3a
is lesser, which is good I suppose. But the function comment is no longer
accurate...

I don't know what to write instead in that comment, but with the new
sort 1.4-p12a < 1.4-p3a, which looks about as bad as 1.4.4a < 1.4-p3a.
Maybe like this:


diff --git a/bootstrap b/bootstrap
index 852efd5..ca2bb11 100755
--- a/bootstrap
+++ b/bootstrap
@@ -1312,9 +1312,9

+# in that it treats 1.5 < 1.5.0, and treats 1.4-p12a < 1.4-p3a
 # but this should suffice as we won't be specifying old

 # If we did want full compatibility then we should probably

But I'm not sure if m4_version_compare handles p12a vs p3a, so
I'll leave this for Gary to clean up.
