Finuxm status.

these changes are inspired by Koji Arai. Thanks.
* process.c (proc_wait): should not iterate if pid_tbl is 0.
* process.c (proc_waitall): ditto.
* numeric.c (flodivmod): a bug in no fmod case.
* process.c (pst_wifsignaled): should apply WIFSIGNALED for status
(int), not st (VALUE).
* io.c (Init_IO): value of $/ and $\ are no longer restricted to
strings. type checks are done on demand.
* class.c (rb_include_module): module inclusion should be check
taints.
* ruby.h (STR2CSTR): replace to StringType() and StringTypePtr().
* ruby.h (rb_str2cstr): ditto.
* eval.c (rb_load): should not copy topleve local variables. It
cause variable/method ambiguity. Thanks to L. Peter Deutsch.
* class.c (rb_include_module): freeze check at first.
* eval.c (rb_attr): sprintf() and rb_intern() moved into
conditional body.

* What's Ruby
Ruby is the interpreted scripting language for quick and
easy object-oriented programming. It has many features to
process text files and to do system management tasks (as in
Perl). It is simple, straight-forward, and extensible.
* Features of Ruby
+ Simple Syntax
+ *Normal* Object-Oriented features(ex. class, method calls)
+ *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
+ Operator Overloading
+ Exception Handling
+ Iterators and Closures
+ Garbage Collection
+ Dynamic Loading of Object files(on some architecture)
+ Highly Portable(works on many UNIX machines, and on DOS,
Windows, Mac, BeOS etc.)
* How to get Ruby
The Ruby distribution can be found on:
ftp://ftp.ruby-lang.org/pub/lang/ruby/
You can get it by anonymous CVS. How to check out is:
$ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/home/cvs login
(Logging in to anonymous@cvs.ruby-lang.org)
CVS password: guest
$ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/home/cvs checkout ruby
* Mailing list
There is a mailing list to talk about Ruby.
To subscribe this list, please send the following phrase
subscribe YourFirstName YourFamilyName
e.g.
subscribe Joseph Smith
in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
* How to compile and install
This is what you need to do to compile and install Ruby:
1. If ./configure does not exist or is older than configure.in,
run autoconf to (re)generate configure.
2. Run ./configure, which will generate config.h and Makefile.
3. Edit defines.h if you need. Probably this step will not need.
4. Remove comment mark(#) before the module names from ext/Setup (or
add module names if not present), if you want to link modules
statically.
If you don't want to compile non static extension modules
(probably on architectures which does not allow dynamic loading),
remove comment mark from the line "#option nodynamic" in
ext/Setup.
5. Run make.
6. Optionally, run 'make test' to check whether the compiled Ruby
interpreter works well. If you see the message "test succeeded",
your ruby works as it should (hopefully).
7. Run 'make install'
You may have to be a super user to install ruby.
If you fail to compile ruby, please send the detailed error report with
the error log and machine/OS type, to help others.
