+Subject: [PATCH 3/3] Fix DynamicLibrary to build with musl libc
+
+stdin/out/err is part of the libc and not the kernel so we check for the
+specific libc that does the unexpected instead of linux.
+
+This is needed for making it build with musl libc.

+Subject: [PATCH 2/3] Fix build with musl libc
+
+On musl libc the fopen64 and fopen are the same thing, but for
+compatibility they have a `#define fopen64 fopen`. Same applies for
+fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.
