The problem is how to write the DUMPED and ALLOCATED_BEFORE_DUMPING
macros.  For Cygwin, they use some intimate knowledge about Cygwin
runtime internals; the question is, do other platforms have similar
facilities and features.

There's also the MinGW way of getting rid of gmalloc, but it needs a
different feature: the ability to specify a user-defined sbrk
function (which MS-Windows supports).
