When using the new "configure; make" build process, please
run configure with the --disable-shared option. "Make check" does not
yet pass with dynamic libraries. Ther reasons for that are not yet
understood. (HB, paraphrasing message from Hironori SAKAMOTO.)

__declspec(dllexport) needs to be added to declarations
to support the case in which the collector is in a dll.
GC_DLL User-settable macro that forces the effect of _DLL.
GC_DLL User-settable macro that forces the effect of _DLL. Set
by gc.h if _DLL is defined and GC_NOT_DLL is undefined.
This is the macro that is tested internally to determine
whether the GC is in its own dynamic library. May need
to be set by clients before including gc.h. Note that
inside the GC implementation it indicates that the
collector is in its own dynamic library, should export
its symbols, etc. But in clients it indicates that the
GC resides in a different DLL, its entry points should
be referenced accordingly, and precautions may need to
be taken to properly deal with statically allocated
variables in the main program. Used only for MS Windows.
GC_NOT_DLL User-settable macro that overrides _DLL, e.g. if dynamic
libraries are used, but the collector is in a static library.

<H1>Two-Level Tree Structure for Fast Pointer Lookup</h1>
<P>
The conservative garbage collector described
<A HREF="gc.html">here</a> uses a 2-level tree
<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/">here</a>
uses a 2-level tree
data structure to aid in fast pointer identification.
This data structure is described in a bit more detail here, since
