Can you investigate some more and report your findings back to the list?
Sure.
Thanks for following up.
bash ../../src/configure
--prefix=/export/home/andreask/dbn/BuildTmp/Hwloc/solaris2.8-sparc/install
--exec-prefix=/export/home/andreask/dbn/BuildTmp/Hwloc/solaris2.8-sparc/install
--with-tcl=/export/home/andreask/dbn/BuildTmp/Hwloc/solaris2.8-sparc/install/lib
--with-tk=/export/home/andreask/dbn/BuildTmp/Hwloc/solaris2.8-sparc/install/lib
--enable-shared --enable-threads

The generated Makefile and libtool however have SHELL=/bin/sh
assignments in them, and without me forcing them to use bash they [[fail]].
Ah, I see the problem.
You needn't tell Autotools that you have a preferred shell
Wel, I was not reall aware of telling it about a prefered shell, just executing
configure via bash.
Actually, I am kind of surpised that it is apparently possible to run configure
with a shell A, under which tests are run, and then having it generate files
for a shell B it considers preferable, but was not tested against.

So, is 'configure' re-exec'uting itself with a different shell, if it finds
whatever it prefers ?
[snippet elided]
Generally, bash is an excellent shell to use interactively, but it is a little
buggy and considerably slower

bash is simply the shell of choice here for both interactive and scripting use.
Which we know to have everywhere, with a consistent set of features.
However, you can safely force an alternative shell to execute the various
Autotools scripts by setting both SHELL and CONFIG_SHELL, like so:
./configure SHELL=/usr/local/bin/bash CONFIG_SHELL=/usr/local/bin/bash<other
arguments as usual>
Is it possible to set this through the environment as well ? (It might be
easier for the build setup here to put this into the environment of ./configure
when it is run. Have to re-check).
I should note that SHELL is set in the global environment too, to
'path/to/bash'.
Its apparently only CONFIG_SHELL I might have to set.
That should ensure that SHELL is then set correctly in libtool and Makefile to
match the tests that configure ran earlier.
Thanks for all the help.
