Re: [RFC] Update to current automake/autoconf/libtool versions.

Er, wow!  Few technical hurdles to overcome first.

Anyone know what happens if only half the directories get converted?

There is a problem with libiberty and utils because GCC have their feet 
stuck in the ice (unless src, again splits off from GCC, but I suspect 
here we don't want to).

> bfd binutils gas gdb gprof ld libiberty mmalloc opcodes rda sim utils

bfd, binutils, gas, gprof, ld and opcodes are all BINUTILS.
mmalloc, sim and gdb are all GDB.
I'd drop rda from the list.

I don't understand this:

- 
$(SHELL) $(YLWRAP) "$(YACC)" $(srcdir)/c-exp.y  y.tab.c c-exp.tmp -- 
$(YFLAGS)
+ 
$(SHELL) $(YLWRAP) $(srcdir)/c-exp.y  y.tab.c c-exp.tmp -- "$(YACC)" 
$(YFLAGS)

isn't it independant of the switch?

Same with this?

-  AC_DEFINE(HAVE_LONG_DOUBLE)
+  AC_DEFINE([HAVE_LONG_DOUBLE], [], [Define if the `long double' type 
works])

(or did the new autoconf change the interface causing a warning if the 
three parameters were not present?).
