 657         Fixes for building on 64-bit hosts:
 658         * config/tc-avr.c (mod_index): New union to allow conversion
 659         between pointers and integers.
 660         (md_begin, avr_ldi_expression): Use it.
 661         * config/tc-i370.c (md_assemble): Add cast for argument to print
 662         statement.
 663         * config/tc-tic54x.c (subsym_substitute): Likewise.
 664         * config/tc-mn10200.c (md_assemble): Use a union to convert the
 665         opindex field of fr_cgen structure into a pointer so that it can
 666         be stored in a frag.
 667         * config/tc-mn10300.c (md_assemble): Likewise.
 668         * config/tc-frv.c (frv_debug_tomcat): Use %p to print pointer
 669         types.
 670         * config/tc-v850.c: Replace uses of (int) casts with correct
 671         types.
