This clarifies and fixes some licensing issues raised by Glenn Morris <http://lists.gnu.org/archive/html/bug-gnulib/2011-09/msg00397.html>. It also merges the latest version of texinfo.tex and has some MSVC-related changes that don't affect Emacs. * Makefile.in (GNULIB_TOOL_FLAGS): Avoid msvc-inval, msvc-nothrow, pathmax, and raise, since these are needed only to address MSVC-related issues that Emacs doesn't have. * doc/misc/texinfo.tex, lib/dup2.c, lib/gnulib.mk, lib/signal.in.h: * lib/sigprocmask.c, lib/stat.c, lib/stdio.in.h, lib/sys_stat.in.h: * lib/unistd.in.h, m4/dup2.m4, m4/getloadavg.m4, m4/gl-comp.m4: * m4/include_next.m4, m4/signal_h.m4, m4/signalblocking.m4: * m4/stdint.m4, m4/stdio_h.m4, m4/sys_stat_h.m4, m4/time_h.m4: * m4/unistd_h.m4: Merge from gnulib.

|
fseek module depends on the fseeko module, so we only have three
|
|
cases to consider:
|
|
|
|
1. The developer is not using either module. Issue a warning under
|
|
GNULIB_POSIXCHECK for both functions, to remind them that both
|
|
functions have bugs on some systems. _GL_NO_LARGE_FILES has no
|
|
impact on this warning.
|
|
|
|
2. The developer is using both modules. They may be unaware of the
|
|
arbitrary limitations of fseek, so issue a warning under
|
|
GNULIB_POSIXCHECK. On the other hand, they may be using both
|
|
modules intentionally, so the developer can define
|
|
_GL_NO_LARGE_FILES in the compilation units where the use of fseek
|
|
is safe, to silence the warning.
|
|
|
|
3. The developer is using the fseeko module, but not fseek. Gnulib
|
|
guarantees that fseek will still work around platform bugs in that
|
|
case, but we presume that the developer is aware of the pitfalls of
|
|
fseek and was trying to avoid it, so issue a warning even when
|
|
GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
|
|
defined to silence the warning in particular compilation units.
|
|
In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
|
|
fseek gets defined as a macro, it is recommended that the developer
|
|
uses the fseek module, even if he is not calling the fseek function.
|
|
|
|
Most gnulib clients that perform stream operations should fall into
|
|
category 3. */
