OK. I'll regen the configure.in patch that way.

Note1: the conversion from old-style libtool initialization macros to 
new-style can be done on a case-by-case basis after Steve's current 
update is committed; it needn't be an "all-at-once" megapatch.

Note2: I mentioned that switching to the new macros would require making 
the newlib changes atomically with Steve's update of the toplevel 
libtool.m4&friends.  This is a red herring; _LT_DECL_SED is /also/ only 
provided by the new .m4 files.  So we need to make the newlib and 
toplevel changes atomically, regardless of whether the newlib 
configure.in's use old-style libtool initialization macros or new-style.

This ^^^ looks like Paolo's answer to question (1) from
http://www.cygwin.com/ml/newlib/2007/msg00542.html
is yes.  I still need an answer to (2), probably from Jeff, and then 
I'll redo my whole 10-step procedure and retest tonight.

Once that's done, I'll send Steve the *entire* set of changes (as 
produced mechanically by the scripts I posted earlier
http://www.cygwin.com/ml/newlib/2007/msg00533.html)
along with ChangeLog entries so he can 'absorb' it.
