You are correct that configure reruns itself with a better shell, if the
default is insufficient for its needs, and CONFIG_SHELL was not set
(setting CONFIG_SHELL is useful in part as a torture test of autoconf
being able to work in spite of insufficient shells, but also so that you
can manually choose a better shell rather than wasting configure's time
finding it).  Does adding something like address@hidden@ to
Makefile.in help your situation?

The autoconf manual discusses the use of CONFIG_SHELL.
