1998-04-07 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/_G_config.h (_G_stat64): Define to stat64. (_G_OPEN64, _G_LSEEK64, _G_FSTAT64): Use namespace clean functions. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Add __lseek64 alias for __llseek. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/llseek.c: Likewise. * sysdeps/generic/lseek64.c (lseek64): Rename to __lseek64, and make it a weak alias. * posix/unistd.h: Declare __lseek64. * libio/fileops.c (fstat) [_LIBC]: Use namespace clean function. (_IO_file_stat): Fix typo. (_IO_file_xsgetn): Update fd->_offset. Read a multiple of the block size from the file. Use __mempcpy if _LIBC.
