+Subject: [PATCH] args.h: add missing <cstdint> include for int64_t
+
+args.h declares getAutotuneModelSize() returning int64_t but never
+includes <cstdint> itself. On glibc/libstdc++ this compiles because
+some other transitively-included standard header happens to declare
+int64_t first, but that is not guaranteed. musl's libc++/libstdc++
+headers do not provide this transitive declaration, so args.h fails
+to parse with "unknown type name 'int64_t'". The existing
+0001-PATCH-floret patch adds <cstdint> to args.cc, but only after
+it includes "args.h", so it does not help args.h parse itself.
+Include <cstdint> directly in args.h so the header is self-contained.
+
