unlocked-io: do not redefine getc_unlocked etc. I ran into this problem on AIX 7.1 with GNU Tar, which enables visibility of getc_unlocked etc. after testing whether they’re declared, causing argp-namefrob.h and unlocked-io.h to redefine the macros. * lib/argp-namefrob.h, lib/unlocked-io.h: (clearerr_unlocked, feof_unlocked ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unlocked): Do not define if already defined.
