I saw similar errors before, IIRC there were some old MACROS in .m4
files used from inside the package source tree, but never tracked it
really down.  After cleaning up with old buggy .m4 files and
reconfiguring it works in most of the cases.

No, never saw this before.

Is this the original libtool-devel-1.5.10 code before any patches?
If so, then it can't be wrong since I have nearly the whole GNOME
desktop compiled with this libtool (relink on install disabled).

Does it help with the errors you're getting if you use your version?
