thanks

I'm not sure why this bug got closed.  Regardless of what I said about
gNewSense and its lack of NSFontDescriptor implementation, the GNUstep
port of Emacs still fails to build on a fairly modern Debian system
with the latest GNUstep stable release installed:

$ dpkg -l libgnustep-gui-dev
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad)
||/ Name           Version        Description
+++-==============-==============-============================================
ii  libgnustep-gui 0.16.0-2       GNUstep GUI header files and static librarie

This is only because the type definitions and method declarations are
in NSFontDescriptor.h, which is not included neither from AppKit.h nor
from the related NSFont headers.  A simple #import of this header in
nsfont.m fixes this.  Not an Emacs bug, I believe, but easy to
workaround, at least temporarily.

The specific error message follows.
