+Subject: [PATCH 1/3] ISO C23: Backport stdbool.m4
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Petr Písař <ppisar@redhat.com>
+
+The bundled gnulib check for stdbool.h did not account for ISO C23
+which provides its own false and true keywords. As a result stdbool.h
+presence was not correctly detected and libopts/compat/compat.h,
+bundled from AutoGen, failed to compile with GCC 15 which defaults to
+ISO C23:
+
+    In file included from autoopts/project.h:30,
+                     from libopts.c:2:
+    ./compat/compat.h:188:19: error: cannot use keyword ‘false’ as enumeration
+constant
+      188 |    typedef enum { false = 0, true = 1 } _Bool;
+          |                   ^~~~~
+    ./compat/compat.h:188:19: note: ‘false’ is a keyword with ‘-std=c23’ onwards

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Petr Písař <ppisar@redhat.com>
+
+With GCC 15, which defaults to ISO 23, a build failed, for example like
+this:
+
+    gcc -DLOCALEDIR=\"/usr/local/share/locale\" -DHAVE_CONFIG_H -I. -I..
+-I../libopts -I. -I.. -I../lib -I
+    ../lib -I../intl  -Wno-format-contains-nul -g -O2 -Wno-format-contains-nul
+-c -o shar.o shar.c
+    In file included from local.h:23,
+                     from shar-opts.h:354,
+                     from shar.c:46:
+    ../lib/system.h:78:7: error: conflicting types for ‘fdopen’; have ‘FILE
+*(void)’
+       78 | FILE *fdopen ();
+          |       ^~~~~~
+
+The cause is that ISO C23 changed a meaning of an empty argument list
+from an unspecified list to no arguments.
+
+Also K&R syntax is now deprecated and the compiler warned:
+
+    encode.c: In function ‘write_encoded_bytes’:
+    encode.c:33:1: warning: old-style function definition
+[-Wold-style-definition]
+       33 | write_encoded_bytes (group, file)
+          | ^~~~~~~~~~~~~~~~~~~
+
+This patch fixes both the erros and the warnigs by specifying all the
+arguments in the modern syntax.
