capa should be even number on 64-bit SPARC for 8-byte word alignment
* id_table.c (list_id_table_init): When unaligned word access is prohibited and sizeof(VALUE) is 8 (64-bit machines), capa should always be even number for 8-byte word alignment of the values of a table. This code assumes that sizeof(ID) is 4, sizeof(VALUE) is 8, and xmalloc() returns 8-byte aligned memory. This fixes bus error on 64-bit SPARC Solaris 10.
