Perhaps I am missing the point here. I must admit I'm pretty lost with
autoconf/automake, spending more time worrying about automake/autoconf
issues than actually writing the C for the program!

But I have found several m4 macros of use, that are on the web for
autoconf. There is a whole bunch of them at
http://www.gnu.org/software/ac-archive/htmldoc/index.html
that are useful. 

I'm using 3 - one to find gtk
(can't recall where that came from)
another to find the right compiler and compiler switches for
multi-threded programs 
http://www.gnu.org/software/ac-archive/htmldoc/acx_pthread.html
another to check the correct version of gsl exists (the one that is
causing me grief). 

I'm likely to add another one to determine how to compile code to use
the MPI library for distributed processing. 
http://www.gnu.org/software/ac-archive/htmldoc/acx_mpi.html

All these have .m4 extensions and are reasonably well documented. i.e. 
ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
with full documentation. Just what I want. 

How am I supposed to use these ? The gtk.m4 and acx_pthread.m4 seemed
to work okay with the 'sinclude(filename.m4)' but not the one for the
gsl library, which is part of the latest GNU gsl-1.3 distribution. 

Reading around the web I see sinclude should not be used any more, and
references to m4_sinclude. But that don't seem to work much better.

There is a section in the autoconf manual on m4 programing
http://www.gnu.org/manual/autoconf/html_node/autoconf_89.html#SEC89
but it don't make it too clear to me how to use the macros once they
are written. 

Here are my current set of error messages and the complete
configure.ac file. Any help appreciated.
