begin quoting Eric Sunshine as of Sat, May 01, 2004 at 10:43:47PM -0400: [snip] > Perhaps this configure script was generated from a CVS version of Autoconf > in which the shell selection and "missing shell function" reporting were > rather buggy.

Apparently you were correct, as obtaining autoconf 2.59, recreating the configure script from the configure.ac file, and re-running ./configure ends up running to completion. (About all I had to do was set the M4 environment variable, despite GNU m4 1.4 being in /usr/local/bin, and /usr/local/bin heading up my PATH in front of /usr/ccs/bin.) Thanks again. -Stewart
