Dear Sir,
Never uderestimate the ingenuity of fools.
I thought that for reasons unknown I _should_ be defining BACKTRACE in
config.h and that the problem was therefore that it was not being found
... in libc.
With no #define HAVE_BACKTRACE 1 in config.h, configure detects that
there is no backtrace
checking for strsep... yes
Step 5. Looking for required system libraries....
checking for dlopen in -ldl... no
checking for backtrace in -lc... no
checking for crypt... no
checking for crypt in -lc... no
checking for crypt in -lcrypt... yes
checking for kstat_lookup in -lkstat... no
Does it compile ? Yes ! After autoconf && automake && gmake
So, my failing to run autoconf after changing config.h caused this waste
of your time ?

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
from Meditation 17, J Donne.
