One regression for 2.22.30 vs 2.22.29 on OpenSolaris 5.10, both x86pc and sun4v,
possibly related to this machine having an older shell:

   $ ./configure
   ...
   ...
   checking whether btowc(EOF) is correct... yes
   checking whether this system has an arbitrary file name length limit... yes
   checking for closedir... yes
   ./configure: bad substitution

Running diff on 'configure' between versions 2.22.29 and 2.22.30, this might be 
the culprit:

   if test $HAVE_CLOSEDIR = 0 || test $REPLACE_CLOSEDIR = 1; then

Trying to isolate it, gives (on that OpenSolaris 5.10 i86pc machine):
===
  $ cat 1.sh                                           
  #!/bin/sh
  test -z "${host_os##os2*}"

  $ ./1.sh
  ./1.sh: bad substitution

Just a guess, but perhaps the recent OS/2 patches to gnulib are the source 
(since 29 vs 30's difference is updated gnulib).
