For my fast back-prop sources that were recently posted I
received a report from Mark Plumbley that on a Sun SparcStation 1
running version 4.0.3 of the OS, rand() returns a value in the
range 0 to 2**31 - 1 whereas on Sys V, rand() returns a value
in the range 0 to 2**15 - 1.  His fix is to replace rand() with
(rand() & 32767).
