* admin/merge-gnulib (GNULIB_MODULES): Add stringeq. With current Gnulib it is already present as in indirect dependency; listing it here because Emacs now depends on it directly. * lib-src/ebrowse.c, lib-src/etags.c: (streq): Remove, as Gnulib defines this now. * lib/fseterr.c, lib/fseterr.h, lib/issymlink.c, lib/issymlink.h: * lib/issymlinkat.c, lib/stdio-consolesafe.c, lib/string.c: * m4/fseterr.m4, m4/gettext_h.m4, m4/stringeq.m4: New files from Gnulib. * src/conf_post.h (tzfree) [__ANDROID_API__ >= 35]: Remove.

/* Maximum number of bytes to read or write in a single system call.
|
|
This can be useful for system calls like sendfile on GNU/Linux,
|
|
which do not handle more than MAX_RW_COUNT bytes correctly.
|
|
The Linux kernel MAX_RW_COUNT is at least INT_MAX >> 20 << 20,
|
|
where the 20 comes from the Hexagon port with 1 MiB pages; use that
|
|
as an approximation, as the exact value may not be available to us.
|
|
|
|
Using this also works around a serious Linux bug before 2.6.16; see
|
|
<https://bugzilla.redhat.com/show_bug.cgi?id=612839>.
|
|
|
|
Using this is likely to work around similar bugs in other operating
|
|
systems. */
