 Hmm, it looks like there is a problem with the gnusrc.tgz archive.
 Because a cvs checkout has the execute bit set:
 
 ls -la src/gnu/dist/gdb6/gdb/observer.sh 
 -rwxr-xr-x  1 root  wheel  4020 Jul  2  2006 src/gnu/dist/gdb6/gdb/observer.sh
 
 But checking the gnusrc.tgz from 
ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/source/sets/
 has this:
 
 -rw-rw-r--  1 root     wsrc        4020 Jul  2  2006 
usr/src/gnu/dist/gdb6/gdb/observer.sh
 
 The the 5.0 and 5.0.1 gnusrc.tgz archives are also missing the executeable bit.
