+# -w used to sit here and suppressed every diagnostic in the build, including
+# the one that mattered: `%I64d` is MSVC-only, glibc mis-parses it as the GNU
+# `I` flag with a width of 64 and an `int` conversion, and the resulting vararg
+# desynchronisation segfaulted the node while logging a received block (issue
+# #5, deterministic at height 1062 -- the first block carrying a real
+# transaction). GCC had been reporting it all along:
+#
+#   warning: format '%d' expects argument of type 'int',
+#            but argument 4 has type 'int64_t'
+#
+# -w cannot be narrowed: it wins over any -W or -Werror= that follows it, so it
+# has to go. The four -Wno- entries below are the categories this 2009-era tree
+# genuinely produces (measured: 248 deprecated-declarations, 157 write-strings,
+# 18 narrowing, 1 unused-result); silencing them by name instead of silencing
+# everything keeps the build quiet while leaving format errors fatal.

+# without -DBITFLASH_NO_GUI, and the two must not overwrite each other.
