There is some fix for sysdeps/unix/readdir_r.c in original 
glibc-2.3/patches/ in 001_orig.diff. This is not included 
in glibc-2.3-head/patches/.

Ideally someone with deep knowledge of original glibc-2.3
(Aurelien ? , Robert ?) could comment for each remaining patch 
in trunk/glibc-2.3/patches/ whether should be included also
in glibc-2.3-head/patches/


already included:
-----------------
002_triplet_change.diff
004_no_nfs_h.diff
008_features.diff

020_linuxthreads.diff	(partially)
022_rpcgen.diff
024_glob_h.diff 
027_regex_h.diff
	

to be (partially) decided:
