Argh. Thanks for that. I was thrown off slightly by the fact that the
raw tarball mixes 2.59 and 2.61, but on looking closer it's only fixincludes
that was generated by 2.61, so I guess it still matters elsewhere.
I'm a bit surprised that I didn't get an error, when binutils /does/ give
an error, and the binutils error comes from a macro called

Well, if gcc isn't /supposed/ to work with newer autoconf, there /is/ no
second problem! As to the first problem: I need to modify
extra_ldflags_libjava before it gets AC_SUBST'd:
@@ -808,6 +809,9 @@ arm*linux*eabi)
+ extra_ldflags_libjava='-lws2_32 -lintl'
... I think it's the right place for a bit of target-os-related configury
such as that.
Anyway thanks for pointing out something I should have remembered myself :)
