* scripts/abilist.awk: If variable `parse_names' is set, grok the file
header lines and write out foo.symlist files for each foo.so.NN listed. * libio/libioP.h (_IO_wfile_jumps): Remove attribute_hidden. This symbol is exported, and we don't want to hide it. Add libc_hidden_proto instead. (_IO_file_jumps): Add libc_hidden_proto. * libio/wfileops.c (_IO_wfile_jumps): Add libc_hidden_data_def. Remove INTVARDEF. * libio/fileops.c (_IO_file_jumps): Likewise. * libio/stdfiles.c: Don't use INTUSE on them. * libio/iofdopen.c (_IO_new_fdopen): Likewise. * libio/iofopen.c (__fopen_internal): Likewise. * libio/freopen.c (freopen): Likewise. * libio/freopen64.c (freopen64): Likewise. * libio/iovdprintf.c (_IO_vdprintf): Likewise.
