+Subject: [PATCH] Allow large file support with musl
+
+USE_LARGEFILES requires the libc to define _LFS64_LARGEFILE and errors
+out otherwise. musl does not define it: its off_t is always 64-bit and
+lseek64(), mmap64() and friends are aliases of the plain interfaces.
+So the build fails on musl:
+
+  ./constants.h:36:2: error: no large file support available, remove -DLARGEFILES from makefile
+
+When _LFS64_LARGEFILE is missing, only require a 64-bit off_t.
+
+Also replace the %L length modifier on integer conversions with the
+standard %ll. %L is only defined for long double, and musl's printf
+rejects it with integer conversions.
+
+Upstream-Status: Pending
