+Subject: [PATCH] include/woff2/output.h: add missing <stdint.h> include
+
+Without the change `woff2` build fails on upcoming `gcc-15` as:
+
+    In file included from src/woff2_out.cc:9:
+    include/woff2/output.h:73:25: error: expected ')' before '*' token
+       73 |   WOFF2MemoryOut(uint8_t* buf, size_t buf_size);
+          |                 ~       ^
+          |                         )
+    include/woff2/output.h:79:3: error: 'uint8_t' does not name a type
+       79 |   uint8_t* buf_;
+          |   ^~~~~~~
+    include/woff2/output.h:16:1: note: 'uint8_t' is defined in header '<cstdint>';
+      this is probably fixable by adding '#include <cstdint>'
