libiberty fix

[Trevor Forbes]

Well, I tried the first "Chris" CVS fix and for me (which seems to be
opposite to everyone else), Cygwin built perfectly, unfortunately Insight
did not....

I tried Chris's last patch (configure.tar.bz2) and both Cygwin and Insight
built perfectly. I even rebuilt both again using the new cygwin1.dll with no
troubles.......  Also, all the Cygwin make check tests pass.....

# of expected passes           85
# of expected failures          17

For info, I build using Win2k.

I do not know why I am seeing differing results?
