Subject: [PATCH] [Oops, I forgot half of the patch.] Patch # 1050 by Amaury
 Forgeot d'Arc. On Windows, debug builds insert stack probes, and recursive
 functions tend to exhaust the stack faster. This patch reduces the marshal
 maximum depth from 2000 to 1500 for debug builds only. Optimized builds are
 not affected. This allows test_marshal to pass with debug builds.
