No. But if you use MS-LINK, and get the overlay obj file from their
C runtime library, you can do msc-style overlays with ZTC++. (The overlay
stuff is supported by the startup code.)

Note: because MS-LINK does not load overlays called via pointers to
functions, you cannot have virtual functions reside in overlays.

We're investigating doing overlays for the next version.
