Update.
2002-07-24 Ulrich Drepper <drepper@redhat.com> * libio/fileops.c (_IO_file_seekoff_mmap): Do use fp->_offset to compute current position. * stdio-common/tst-fseek.c (main): Improve error messages. * libio/tst-freopen.c (main): Remove unused variable. * libio/fileops.c (_IO_file_seekoff_mmap): Set fp->_offset after succesful seek call. Simply error checking. 2002-07-25 Jakub Jelinek <jakub@redhat.com> * config.h.in: Use __ASSEMBLER__ test macro not ASSEMBLER. * sysdeps/ia64/fpu/libm_support.h: Likewise.
