First question:  what shell is configure actually running under?

Autoconf makes an effort to find a plausible POSIX shell, and /bin/sh on 
Solaris 10 is not it.  The copy of bash-3.2 you used for interactive 
testing was probably not it either.  I seem to recall that grepping 
config.status for CONFIG_SHELL should tell you.

Off the top of my head, try `CONFIG_SHELL=/full/name/of/bash-3.2 
configure` and see if the test works.

I am not so certain that this is exactly a rookie mistake---it looks 
like you may have uncovered a shell bug, but in which shell?
