The *-rtems4* toolchains I supply for RTEMS currently are hosted on CentOS5+6, openSUSE 11.3+12.1, Fedora 15+16+17, mingw32 and cygwin, using these OSes' native toolchains. Other folks have reported to build these toolchains under different *BSDs and MacOSX variants. That said, in my understanding, the rtems targets entries on your table do not make much sense, because the limiting factor is the host-OS. From my list above, the oldest native compiler being in use are Cygwin's GCC-3.4.4 and CentOS5's gcc-4.1.2. Ralf
