OK, I now have:

So the problem with len disappears, but I still get a failure:

(cd .libs && gcc  -I/progs/SUNWspro/WS6U2/include -c -fno-builtin "guileS.c")

However, If I add 
LDFLAGS=-L/progs/SUNWspro/lib
export LDFLAGS

This doesn't help.

Having 

CFLAGS="-I/progs/SUNWspro/WS6U2/include -L/progs/SUNWspro/lib"
export CFLAGS

also fails:

At which point I am now stuck.  After all, configure found isinf.

doing: 
mv ./configure ./configure.orig
cp ./configure.orig ./configure
autoreconf -if
(with autoconf 2.61)  I get a vastly different configure script
with spurious "-n"s sprinkled throughout:

which therefore doesn't work.  There are lots of differences, enough 
that my original commands get lost off the top of a 2000 line scroll buffer.

I think I am out of my depth now.
