anything more reliable than this?

~ > ruby -rrbconfig -e'p File.join(*Config::CONFIG.values_at("bindir","RUBY_INSTALL_NAME"))'
"/usr/local/bin/ruby"

It doesn't, but EXEEXT is not needed by system and spawn.

does this do anything tricky on windows like it does on *nix:

system "#{ cmd } 2>/dev/null"

As well as command.com/cmd.exe, some suffixes can be omitted.

It would work except that:
* redirection with file descriptor works only on cmd.exe, but
not command.com, and
* /dev/null doesn't exist on Windows.

I believe it exists (not sure if on *ALL* versions) as
"NUL". Notice that it is spelt with a single L
