Log: For newer FreeBSDs the return type of malloc() and free()

             is being guessed wrong because the 5.005 configure doesn't
             check that if the malloc.h exists that it doesn't simply do
             "#error ..." as it does in a number of more recent OS -
             I've copied in the test from the blead Configure and
             jiggled a few things around and all is hunk-dory - with
             this everything compiles and tests fine on
             FreeBSD 6.2-RELEASE-p4 (Thanks to Jonathan Stowe)
