Martin,

The reason for Joel's patch of a few months ago is due to the fact
that some versions of AIX contain a libpthdebug that's too old for
aix-thread.c.  See:

    http://sources.redhat.com/ml/gdb-patches/2002-11/msg00705.html

You haven't reverted the portion which conditionally pulls in
aix-thread.o.  But you have backed out the portion which causes
-lpthdebug to be positioned at an inopportune location on the link
line.  Setting it via NAT_CLIBS will always cause gdb (for native AIX)
to be linked against libpthdebug.  That *should* be okay.  (I'm not
completely certain though.)

Just out of curiosity, did you try changing:

         CONFIG_LDFLAGS="${CONFIG_LDFLAGS} -lpthdebug"

to:

         LIBS="${LIBS} -lpthdebug"
?

If this works, I like it better...
