Subject: [ruby-talk:15711] bug in "system" PATH scanning?

--=-=-=

% cd /tmp
% PATH=.:$PATH ruby -e 'p system("ruby -v")'
ruby 1.6.3 (2001-03-22) [i586-linux-gnu]
true
% mkdir ruby
% PATH=.:$PATH ruby -e 'p system("ruby -v")'
false

Aka, if you have a directory named the same as the binary before the binary in
the search path, it will fail.

This patch fix it.
