2002-07-17 Jeff Johnston <jjohnstn@redhat.com> * configure.host(stdio64_dir): New setting that is used to enable building of new stdio64 directory. * libc/Makefile.am[HAVE_STDIO64_DIR]: Add support for large files. (stmp-stdio64,stdio64.texi): New targets to optionally add in stdio64 info to info files. * libc/Makefile.in: Regenerated. * libc/configure: Ditto. * libc/configure.in: Add configuration variables that are set when stdio64 is selected as subdir in configure.host. * libc/libc.texinfo: Add optional menu item for Stdio64, based on whether STDIO64 flag is set or not. * libc/sys.tex: Add optional stdio64 syscalls based on whether STDIO64 flag is set or not. * libc/include/reent.h[__LARGE64_FILES]: Add new stdio64 _r sycall routines. * libc/include/stdio.h[__LARGE64_FILES]: Add new stdio64 prototypes. (FILE): Typedef'd to __FILE instead of struct __sFILE directly. (__SL64): New file flag indicating file is opened via fopen64. * libc/include/sys/_types.h(_off64_t): Added. * libc/include/sys/config.h: For x86-linux, define __LARGE64_FILES. * libc/include/sys/reent.h(struct __sFILE64): New file structure for 64-bit offset large file support. (__FILE): New intermediate type either set to struct __sFILE64 or struct __sFILE, depending on whether __LARGE64_FILES is set or not. * libc/reent/Makefile.am[HAVE_STDIO64_DIR]: Add new files. * libc/reent/Makefile.in: Regenerated. * libc/reent/fstat64r.c: New file. * libc/reent/lseek64r.c: Ditto. * libc/reent/open64r.c: Ditto. * libc/reent/reent.tex: Optionally add stdio64 reentrant syscalls based on whether STDIO64 flag is set. * libc/stdio/stdio.tex: Add blank line. * libc/stdio64/Makefile.am: New file. * libc/stdio64/Makefile.in: Ditto. * libc/stdio64/fgetpos64.c: Ditto. * libc/stdio64/fopen64.: Ditto. * libc/stdio64/freopen64.c: Ditto. * libc/stdio64/fseeko64.c: Ditto. * libc/stdio64/fsetpos64.c: Ditto. * libc/stdio64/ftello64.c: Ditto. * libc/stdio64/local64.h: Ditto. * libc/stdio64/stdio64.c: Ditto. * libc/stdio64/stdio64.tex: Ditto. * libc/stdio64/tmpfile64.c: Ditto. * libc/sys/linux/io64.c: Add weak aliases for lseek64, fstat64, and open64.
