      I don't believe that you can import a class that's not in a package.   I think this has been true since about 1.4.x or so.  You might try putting A in a package, say, mypackage, and then use

      import mypackage.*;

      Stefano -
      I don't know enough about importing from the unnamed package to say
      whether this is a bug or not.  However, if it is a bug, the bug is not
      in Gel.  Gel does not compile, it just uses whatever compiler or
      compilers you have set up to be used by Gel.

      Two notes:
      1)  The Java Language Specification in 7.4.2 says "For this reason, it
      is strongly recommended that compilation units of named packages never
      import types from unnamed packages. It is also recommended that any
      type declared in an unnamed package not be declared public, to keep
      them from accidentally being imported by a named package."

      2)  At URL  http://bdn.borland.com/article/0%2C1410%2C29710%2C00.html
      it is claimed that "Importing a packageless class is illegal according
      to the Java Language Specification (JLS) and always has been."

      You may want to rethink the structure of your program.
      Good Luck!
