Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the

non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.

+
+Building GCC 2.0 for 680x0 based Apollo systems requires the GNU
+assembler (GAS) version 1.38.1, with John Vasta's patches applied.
+
+If you haven't done so yet, get `gas-1.38.1.tar.Z' from your favourite
+GNU distribution site.  Furthermore, get `apollo-gas-1.38.1.diffs'
+from `labrea.stanford.edu:/pub/gnu', apply the patches, compile and
+install gas (under the name as).  This should go through without any
+problems.
+
+After switching into the BSD environment, you can configure GCC 2.0
+with the command 
+
+% ./configure m68k-apollo-bsd
+
+The Apollo's `/usr/include/setjmp.h' uses a nonstandard `#options()'
+construct.  You should create a local copy of this file and remove
+these constructs from the declarations of SIGSETJMP and SIGLONGJMP.
+
+The Apollo's `/usr/include/sys/types.h' (BSD Version) doesn't allow
+to test for the definition of `size_t'.  This should be fixed by
+
+  #ifndef _SIZE_T
+  #define _SIZE_T
+  typedef	long	size_t;
+  #endif
+
+The script `patch-apollo-includes' fixes these two problems, but does
+_not_ pretend to be a full fledged `fixincludes' for this system.
+
+If you now follow the standard GCC installation instructions, building
+GCC 2.0 (including G++ 2.0) should proceed without any problems.
+
+NB: Debugging is not yet supported for the Apollo.  If someone wants
+    to do a _big_ favour to the Apollo users, he/she should consider
+    porting the Binary File Description library (BFD) to the Apollo.
+    This library can be found in the gdb-4.x distributions or in the
+    binutils-1.9x distributions.
