+#  - XFLAGS=/DMINEFIELD
+#      Causes PuTTY to use a custom memory allocator, similar in
+#      concept to Electric Fence, in place of regular malloc(). Wastes
+#      huge amounts of RAM, but should cause heap-corruption bugs to
+#      show up as GPFs at the point of failure rather than appearing
+#      later on as second-level damage.
