+Subject: [PATCH 1/2] stdint.h: Fix build with newer clang
+
+Recent versions of Clang introduced definitions for __*INT64_C:
+https://github.com/llvm/llvm-project/commit/33ad474c45e6d7a0de7bc75e15e27cf6cb9ff895
+
+This results in these build errors:
+
+usr/include/bits64/bitsize/stdint.h:27:9: error: '__INT64_C' macro redefined [-Werror,-Wmacro-redefined]
+   27 | #define __INT64_C(c)  c ## L
+      |         ^
+<built-in>:194:9: note: previous definition is here
+  194 | #define __INT64_C(c) c##L
+      |         ^
+
+Renaming these macros to something more unique avoids the errors.

+Subject: [PATCH 2/2] mount_opts: Fix the mount_opts str length
+
+Newer versions of LLVM report:
+
+usr/utils/mount_opts.c:20:3: error: initializer-string for character array is too long, array size is 8 but initializer has size 9 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
+   20 |         {"diratime", MS_NODIRATIME, 0, MS_NODIRATIME},
+      |          ^~~~~~~~~~
+
+This is indeed a bit odd. "diratime" is 9 bytes long with the \0
+terminator but placed into a struct that uses a static length of 8 bytes
+for that buffer. I suppose this can cause all sorts of undefined
+behaviors in theory but that in practice this never caused anything bad
+because the next field is an unsigned long containing 2048 so the upper
+bytes are 0 and act as string terminators by chance.
+
+Anyway, fixing this helps unblock builds with newer toolchains.
