Expected; use './configure --enable-changeword' if you want that feature
enabled in m4, with the caveat that it will be withdrawn in m4 2.0 (in
favor of a more powerful and faster changesyntax feature).

Thanks for the trace.  That occurs after the damage is already done; how
about setting a breakpoint at line 110 (the call to frexp), and stepping
through that?  Also, is rpl_frexp in use, or is gnulib deferring to your
native frexp?
