+Subject: [PATCH] t2scan: fix -std=c23 build failure
+
+gcc-15 switched to -std=c23 by default:
+
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=55e3bd376b2214e200fa76d12b67ff259b06c212
+
+As a result `t2scan` fails the build so only typedef int bool
+for __STDC_VERSION__ <= 201710L (C17)
+
+    ../tools.h:35:15: error: two or more data types in declaration specifiers
+       35 |   typedef int bool;
+          |               ^~~~
