I've had a look at test_source.c and related files, and can't see anything
obvious... I wondered if it might be caused by another inappropriate setting
in config.h.

I'd be happy to run any further diagnostics you suggest, but I can't afford
the time to attempt further debugging myself.  I must confess I've found
following all the definitions a bit of an uphill struggle (my C experience
is somewhat limited).  I'll have to use the:

  -xchar=unsigned

option to resolve the issue for the moment, though I'd prefer to get to the
bottom of it.  Do you know if other people have installed GSL on Solaris
without getting this problem? - perhaps it's just never been reported before?
