Thanks; I installed that. >> gnulib-tool assumes Autoconf 2.57 through 2.59, since it copies >> m4/onceonly_2_57.m4. > > Does m4/onceonly_2_57.m4 break with autoconf-2.60? I haven't tried it. I hope it works, and don't see why it wouldn't work. I haven't tested it, though. For my own stuff I was planning to just switch to 2.60 and stop using onceonly_2_57.m4. > It produces smaller code, by using some undocumented hooks of > autoconf.

Autoconf 2.59c (soon 2.60) uses the m4/onceonly_2_57.m4 code, not the m4/onceonly.m4 code. So (unless I'm missing something) your hope will be realized.
