Bruce Evans' bcc C compiler.

It is able to handle 16-bit code as well, and comes with an own
assembler and loader.  (They are already known from Minix and Linux as
the `bin86' package.)

With a bit of `dd' magic, bcc can be used to compile messdos programs.

+.Ss Overview
+.Nm As86
+is an assembler for 8086 or 80386 CPUs.  Its syntax resembles rather
+the usual 8086 assembler syntax than the AT&T-like syntax as used by
+the system's assembler
+.Xr as 1 .
+
+It can also be compiled to support the Motorola 6809 CPU.  The name
+.Nm as86
+has only been chosen to make it distinct from the system's assembler.

+
+The

+and
+.Fl w
+options are perhaps back to front because they are needed for cc1
+output and Minix's make does the wrong thing with .s files left

+assemble with them turned off.

+bcc - Bruce's C compiler (with assembler and loader); can do 16-bit code

+This is Bruce Evans' C compiler and binutils package.
+
+
+Either the compiler as the assembler are able to generate 16-bit code.
+Hence it's possible to compile BIOS and DOS code under unix.
+
+The C compiler does understand K&R1 syntax, with a few restrictions
+regarding bitfields.  See the file work/bcc/bcc-cc1/bcc.bugs for
+Bruce's bug list.
+
+The binutils (assembler and loader) have been renamed to as86 and ld86
+to not conflict with the system's assembler and loader, but they are
+also available in the regular BINDIR (normally /usr/local/bin).
+
+It's also possible to generate MC 6809 code with bcc/as.  (This is a
+compile-time option however, and not supported by the binary package
+as it comes with FreeBSD.)
