Fix fseeko/ftello on cygwin 1.5.24. * doc/functions/fseeko.texi (fseeko): Document the fix. * doc/functions/ftello.texi (ftello): Document the fix. * doc/functions/stdin.texi (stdin): Document the cygwin bug. * doc/functions/stdout.text (stdout): New file. * doc/functions/stderr.text (stderr): New file. * doc/gnulib.texi (Function Substitutes): Use new files. * tests/test-fseeko.c (main): Check for broken fseeko on cygwin prior to 1.7.0. * tests/test-ftello.c (main): Likewise for ftello. * tests/test-fseeko.sh: New file. * tests/test-ftello.sh: New file. * modules/fseeko-tests (Makefile.am): Ensure test-fseeko is run with seekable stdin. * modules/ftello-tests (Makefile.am): Likewise for test-ftello. * m4/fseeko.m4 (gl_FUNC_FSEEKO): Detect the cygwin bug. (gl_REPLACE_FSEEKO): New macro. * m4/ftello.m4 (gl_FUNC_FTELLO, gl_REPLACE_FTELLO): Likewise. * modules/fseeko (Files): Distribute fseeko.c. * modules/ftello (Files): Distribute ftello.c. * lib/fseeko.c (rpl_fseeko) [__CYGWIN__]: Convert stdin to 64-bit mode. * lib/ftello.c (rpl_ftello): New file. * m4/stdio_h.m4 (gl_STDIO_H_DEFAULTS): Allow replacement of fseeko, ftello. (gl_STDIN_LARGE_OFFSET): New macro. * modules/stdio (Makefile.am): Perform the replacement. * lib/stdio_.h (rpl_fseeko, rpl_ftello): Define when needed.

@node ftello @section @code{ftello} @findex ftello POSIX specification: @url{http://www.opengroup.org/susv3xsh/ftello.html} Gnulib module: ftello Portability problems fixed by Gnulib: @itemize @item This function is missing on some platforms: OSF/1 4.0, Solaris 2.5.1, mingw. @item The declaration of @code{ftello} in @code{<stdio.h>} is not enabled by default on some platforms: glibc 2.3.6. @item This function fails on seekable stdin, stdout, and stderr: cygwin 1.5.x. @end itemize Portability problems not fixed by Gnulib: @itemize @item On platforms where @code{off_t} is a 32-bit type, @code{ftello} does not work correctly with files larger than 2 GB. The fix is to use the @code{AC_SYS_LARGEFILE} macro. @item @code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly on input streams that are opened in @code{O_TEXT} mode and whose contents contains Unix line terminators (LF), on some platforms: mingw. @end itemize
