* coff-sh.c (bfd_pe_print_pdata): Define to NULL for non
COFF_WITH_PE based SH ports. * libpei.h (_bfd_XX_print_ce_compressed_pdata): Prototype. * arm-wince-pe.c (bfd_pe_print_pdata): Use _bfd_pe_print_ce_compressed_pdata. (slurp_symcache, cleanup_syms, pe_print_ce_compressed_pdata): Move to... * peXXigen.c: ... here and rename pe_print_ce_compressed_pdata to _bfd_XX_print_ce_compressed_pdata.
