	I also don't want to enter any religious war, but maybe
some more information may be interesting to *BSD potential
users of Gnat. As far as I know, there are versions of Gnat
for NetBSD/i386 and NetBSD/ARM, and for FreeBSD (no tasking yet).
Since OpenBSD is capable of running NetBSD executables, OpenBSD
also counts as `ported platform'.

	The FreeBSD port has been done by cross-compiling from
SunOS, AFAIK, and the process doesn't seem to be that complex. It
sould be of similar complexity getting a BSDI compiler from a 
SunOS (or in fact any other Unix) version. In fact, it should be
easier, since the documentation of the FreeBSD porter (Daniel M. Eischen)
is available
