[Bug libgcj/26177] New: Exception when compiling valid regex pattern

["green at redhat dot com" <gcc-bugzilla@gcc.gnu.org>]

The azureus developers identified a regex failure that is causing trouble...

$ cat /tmp/ar.java
import java.util.regex.*;

public class ar
{
  public static void main (String args[])
  {
    Pattern p = Pattern.compile ("(?i)yoda");
  }
}
$ gcj -C ar.java
$ gij ar
Exception in thread "main" java.util.regex.PatternSyntaxException: At position
1 in regular expression pattern:
quantifier (?*+{}) without preceding token
        (?i)yoda

(Yes, I ran this again 4.0, but the same thing happens in 4.1).
