+# Upstream project is dormant (last release v1.0.3 in 2014). The codebase uses
+# K&R-style function pointer declarations (e.g. void (*funct)()) and redefines
+# bool via typedef, which are incompatible with C23 defaults in GCC 15:
+#   1. bool is a keyword in C23; typedef to bool is a hard error
+#   2. () means zero params in C23; calling through () pointers with args is an error
+#   3. Incompatible pointer type assignments are promoted to errors
+# An upstream fix (partial) exists but is not merged: https://github.com/openbios/fcode-utils/pull/32
+# Fedora has not patched this either as of rawhide (Feb 2026).
+# Force C17 mode to restore pre-C23 semantics until upstream modernizes.
