------- Comment #7 from rob1weld at aol dot com 2009-01-22 14:50 ------- Self Confirmed. Attempting to execute 64 bit code when booted 32 bit:

We need 'gcj-dbtool' to be compiled 32 bit when building the 64 bit library and booted in 32 bit mode to avoid the "dbtool: cannot execute [Exec format error]". Until we have OSes than will _only_ boot 64 bit and will not run 32 bit code (in which case they would not build the other library and this Bug ought not to reoccur) we can build the program 32 bit regardless of which library or boot mode (32 or 64).
