Presumably the problem is that the cc call lacks "-lm".
  

Indeed. Just took me a bit longer to get that. :-)

Checking back against 8.1, I see that 8.1's configure has

	AC_CHECK_LIB(m, main)

where 8.2 tries to do

	AC_SEARCH_LIBS(pow, m)

I suppose there is something funny about pow() on your platform
causing that probe to fail.  What does config.log have at the
"checking for library containing pow" step?
