Hi, fputc_unlocked is gone. Is this another 'libc_hidden_proto' loss? I did a diff of readelf -s output of my working libuClibc.so against trunk and found that even more symbols are gone: < __C_ctype_b_data < __libc_fstatfs < __libc_statfs < _stdio_openlist_dec_use < fputc_unlocked < fwprintf < isascii T.
