09a4374e6d Revert rev 1.7 which moved us away from POSIX character classes.
The community feels our base AWK must handle them.

2273086d55 Substitute "[:space:]" with the character constants it expands to.
This was a silent 'failure' when using Bell-Labs awk.

49acc8fe50 Bring in ficl 2.05.
This version has a step debugger, which now completely replaces the
old trace feature. Also, we moved all of the FreeBSD-specific MI
code to loader.c, reducing the diff between this and the official
FICL distribution.

f9c70d7647 Don't use the Gawkism strftime(). Pass in the date stamp on the awk
command line instead.

23bab6002c Make abort" functional in interpret mode. This behavior is undefined
by ANS Forth standard, but it's useful.

Also, define the constant true in a more strict way. C might garantee
2-complement math, but Forth doesn't.

0812b1e2c9 Fix world-breaking bug, add $FreeBSD$ tag.
This happened to be my first "for real" broken world. I had broken
it once before, but nobody noticed, so it didn't count.

So, how do I get the "I broke world and all I got was the lousy t-shirt"
t-shirt?

98c5378cdc Make FICL_TRACE default.
Add freebsd.fr, for FreeBSD specific forth source. Add $ and %, to
replace the lost @ and - functionality of include. $ has the opposite
behavior of @ though, since the default behavior was inverted.

aa8b85772f Add conditional compilation facilities to ficl. This had been previously
committed to RELENG_3 instead of HEAD, so let's HEAD catch up.

378972ac6b Transition from using Perl to using awk for our text-manipulation
needs.  This removes the dependancy on Perl for the generation of the
loader, allowing the world to be built on a perl-free system.

f476d38a01 Make fexists/fload work with existing string literals instead. Doing
my own string literal handling is just too wonky.

82f35547c9 Remember a bit more of my forth and do:
o Add fexists word to check for the presence of a file
o make fexists and fload immediate words which DTRT both interpreted
  and compiled (doh!)
o add an init word which gets run at bootstrapping time to do extra
  post-coldload initialization (in the default implementation, we
  look for /boot/boot.4th and load it if found).

2cd5cac4ec Improve the assertion testing for successful softword compilation.
The excessive use of assert() vs. robust error checking is annoying.

780ebb4b00 Add the Ficl (Forth Inspired Command Language) interpreter. If all goes well,
this will allow us to manage bloat in the loader by using a bytecoded HLL
rather than lots of C code.  It also offers an opportunity for vendors
or others with special applications to significantly customise the boot
process without having to commit to a divergent code branch.

This early commit is to allow others to experiment with the most effective
mechanisms for integrating FICL with the loader as it currently stands.
