+Subject: [PATCH] texinfo: guard gettext setup calls with ENABLE_NLS
+
+bindtextdomain() and textdomain() are called unconditionally in
+makeinfo, info, texindex and install-info.  When the build is
+configured with --disable-nls the bundled intl/libintl.a is not
+built, so these references are left undefined on hosts whose libc
+lacks gettext (e.g. Android's bionic), breaking the link.
+
+Guard the two calls with #ifdef ENABLE_NLS, which is only defined in
+config.h when --enable-nls (the default) is in effect, so the symbols
+are only referenced when libintl is actually available.

+Subject: [PATCH] gcc: stop falling back to getwd in getpwd
+
+getpwd.c redirected getcwd to the obsolete getwd whenever POSIX/USG/VMS
+was not defined, or when autoconf detected HAVE_GETWD.  Modern C
+libraries such as musl no longer provide getwd, so when gcc is built
+against such a libc the cc1 link fails with an undefined reference to
+getwd.
+
+Drop the getwd fallback entirely and always call getcwd directly; every
+host in practical use today provides the POSIX getcwd.

+Subject: [PATCH] libiberty: also hide sys_nerr from system headers in strerror
+
+strerror.c already renamed sys_errlist to sys_errlist__ while
+including <stdio.h>/<errno.h>, so that a host declaration with
+incompatible qualifiers (e.g. BSD's "const char * const sys_errlist[]")
+would not clash with libiberty's own extern declaration.  It did not do
+the same for sys_nerr, however, so on FreeBSD 15 -- whose <stdio.h>
+declares "extern const int sys_nerr" -- the libiberty extern
+"int sys_nerr" produced a hard "conflicting type qualifiers" error
+and aborted the build.
+
+Rename sys_nerr the same way while including the system headers, as
+upstream gcc 3.1 already does.
