[gecode-users] making macros safe for semicolons

[Denys Duchier]

I had a couple of problems using some of Gecode macros because they
cannot all be safely followed by a semicolon.  Here is a proposed patch
that uses de "do {...} while (0)" pattern to make these macros safe.
This is an old trick that is used a great deal in the Linux kernel.

The patch is against Gecode 2.2.0:
