Hi,
On OSF/1 5.1, the declarations of fseeko() and ftello() are missing by
default. Setting _XOPEN_SOURCE=500 would provide these declarations but
is not the right fix (see previous mail about fchdir()). I'll add this
fix for fseeko and similarly for ftello:
2010-12-19 Bruno Haible <br...@clisp.org>
fseeko: Add missing declaration on OSF/1 5.1.
* lib/stdio.in.h (fseeko): Test HAVE_DECL_FSEEKO, not HAVE_FSEEKO.
* m4/fseeko.m4 (gl_FUNC_FSEEKO): Test whether fseeko is declared.
* m4/stdio_h.m4 (gl_STDIO_H_DEFAULTS): Initialize HAVE_DECL_FSEEKO.
* modules/stdio (Makefile.am): Substitute HAVE_DECL_FSEEKO.
* doc/posix-functions/fseeko.texi: Mention the OSF/1 5.1 problem.
