+#  - XFLAGS=/DMALLOC_LOG
+#      Causes PuTTY to emit a file called putty_mem.log, logging every
+#      memory allocation and free, so you can track memory leaks.
+#
+#  - 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.
