bug#3652: FTBFS: nsfont.m: 'NSFontTraitsAttribute' undeclared

[Yavor Doganov <yavor@gnu.org>]

Package: emacs,ns
Severity: serious
Tags: patch

The GNUstep port fails to build currently following this change:

2009-06-08  Adrian Robert  <Adrian.B.Robert@gmail.com>

	Changes to support :script/:lang/:otf in NS font driver.
	...

I believe it's a bug in GNUstep GUI which I'll report to their
tracker.  For now, I suggest the workaround below.

What's worse is that the NSFontDescriptor class was implemented in GUI
0.13, while gNewSense DeltaH has 0.12.  Do you consider it important
enough to add a fallback code?
