We're getting lots of these warnings for all strto* functions: ../sysdeps/generic/strtol.c: In function `__strtoll_internal': ../sysdeps/generic/strtol.c:357: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:360: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:369: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:372: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:409: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:412: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:457: warning: comparison between signed and unsigned ../sysdeps/generic/strtol.c:460: warning: comparison between signed and unsigned and for printf_fphex: ../sysdeps/generic/printf_fphex.c: In function `__printf_fphex': ../sysdeps/generic/printf_fphex.c:258: warning: signed and unsigned type in conditional expression ../sysdeps/generic/printf_fphex.c:258: warning: comparison between signed and unsigned ../sysdeps/generic/printf_fphex.c:260: warning: signed and unsigned type in conditional expression ../sysdeps/generic/printf_fphex.c:260: warning: comparison between signed and unsigned [...] and for vfscanf.c vfscanf.c: In function `_IO_vfscanf': vfscanf.c:422: warning: signed and unsigned type in conditional expression vfscanf.c:450: warning: signed and unsigned type in conditional expression and for wgenops.c: wgenops.c: In function `_IO_wdoallocbuf': wgenops.c:406: warning: comparison between signed and unsigned wgenops.c: In function `_IO_switch_to_wget_mode': wgenops.c:456: warning: comparison between signed and unsigned wgenops.c: In function `_IO_sputbackwc': wgenops.c:625: warning: comparison between signed and unsigned wgenops.c: In function `_IO_sungetwc': wgenops.c:645: warning: comparison between signed and unsigned The appended patch removes these warnings and fixes also some macro usage in wegenops. Ok to commit? A similar patch as to printf_fphex can be applied to printf_size.c and printf_fp.c. Andreas 2001-01-02 Andreas Jaeger <aj@suse.de> * sysdeps/generic/strtol.c (strtol): Make cnt size_t for correct signedness. * sysdeps/generic/printf_fphex.c (putc): Cast _IO_putwc_unlocked to (int) to avoid warnings. * stdio-common/vfscanf.c (__vfscanf): Make done signed. * libio/wgenops.c (_IO_wdoallocbuf): Use correct wide access macro. (_IO_switch_to_wget_mode): Likewise. (_IO_sputbackwc): Likewise. (_IO_sungetwc): Use wint_t for result. ============================================================ Index: sysdeps/generic/strtol.c --- sysdeps/generic/strtol.c 2000/07/28 17:44:07 1.4 +++ sysdeps/generic/strtol.c 2001/01/02 14:12:56 @@ -1,5 +1,5 @@ /* Convert string representation of a number into an integer value. - Copyright (C) 1991,92,94,95,96,97,98,99,2000 Free Software Foundation, Inc. + Copyright (C) 1991,92,94,95,96,97,98,99,2000,2001 Free Software Foundation, Inc.
