So far, no problems.  I'm gonna go on record in favor of this patch, in 
its 4th incarnation 
(http://cygwin.com/ml/cygwin-patches/2002-q4/msg00222.html).

given that winsup/cygwin/lib/getopt.c(*) still retains its BSD licensing 
and comments, there's no reason to change the (non-)license/public 
domain attribution in egor's pseudo-relocs.c file.  Egor's patch #4 
should be able to be committed as-is.

(*) winsup/cygwin/lib/getopt.c still retains the original 
BSD-with-advert license which is explicitly incompatible with the GPL. 
And since it is the NetBSD variant, it doesn't fall under the 
"rescinded" announcement made by the Berkeley folks:

ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

(the NetBSD folks are quite clear that they LIKE the advertisement 
clause in their license)

However, the FreeBSD folks DO abide by the "rescind clause 3" decision; 
perhaps we should replace our (modified) getopt.c with a similarly 
modified one from FreeBSD?
