The Minix clang compiler tries to interpret "char []" according to some
character encoding and produces a compiler warning when it encounters byte
sequences that are invalid in that encoding. Avoid the warning by using
_unsigned_ char which it treats as arbitrary bytes.
- (help ...) is a macro that quotes everything to be user-friendly
- (help* ...) is the equivalent procedure
- When the user types just `help` or `exit`, the REPL shows a hint
that they are probably looking for `(help)` or `(exit)`.
Stage 0 is supposed to emit compiled versions of system.scm and
compiler.scm. The compiler.scm bytecode wasn't emitted properly
because the emitter put the two files' bytecode in two separate C
variables instead of concatenating them into the same variable as they
should be.
Previously the boot image was kept in the separate file "flisp.boot".
This caused all kinds of problems, as bootstrapping is wont to do. The
biggest problem was finding a portable and convenient pathname for it.
Instead of dealing with all that stuff about how to find the file,
just store the image in a huge C string constant that goes into the
main executable. This necessitates adding a C-string hex dumper into
the Lisp system, and making build.sh slightly more complicated, but
that's a small price to pay for not having to carry a separate file
everywhere we go. Also, flmain.c is a lot simpler now and we don't
have to play around with symlinks.
