Re: JIGS SimpleApp example

[Mathew McBride]

The version of libfreetype6 I'm using does not have the dropped symbols, 
and GSScreenNumber hints that this problem is coming from within core/gui.

Ouch:

 ld -y GSScreenNumber libgnustep-back-010

libgnustep-back-010: reference to GSScreenNumber
ld: warning: cannot find entry symbol _start; not setting start address
libgnustep-back-010: undefined reference to `objc_get_class'
libgnustep-back-010: undefined reference to `GSCurrentContext'

*libgnustep-back-010: undefined reference to `GSScreenNumber'*
