Another problem is that given that the first file determines the the multif= ile pointer size, so 32-bit, there's no point in running in multifile mode beca= use the other 2 files are 64-bit, so incompatible with the multifile. --=20 You are receiving this mail because: You are on the CC list for the bug.
