I'd like to see support of the 80C186.

Also, the new Motorola MPC555, an engine controller with a PowerPC core
and lots of nice peripherals. See
http://mot2.mot-sps.com/press/html/PR980413A.html for a description.

Support for the 80C186 is unlikely any time soon because gcc and g++
do not support any members of the ix86 architecture before the 386.
eCos makes use of a number of very useful language extensions which
are provided by gcc and g++ but not by other compilers, and there are
no plans to support other compilers.

Ports to some other members of the PowerPC family are under
consideration, and I believe this part has been mentioned
specifically. If I find out more I shall let you know.

Can you enumerate these in the FAQ? I see two listed, priority
constructor ordering (required) and selective linking (optional).

I've been using Borland's compiler for some time in the PC 16-bit world
and in embedded system development and I know it supports a
generalization of priority constructor ordering: One can use "#pragma
startup" with a priority code to request that a function be executed
during RTL init. The RTL uses this mechanism to order initialization of
various RTL structures (heap, stdio, FPU emulator). The compiler uses
the same internal structures to implement constructor calls for static
objects.
