+Subject: [PATCH] Sort file lists generated by rscan_dir()
+
+The rscan_dir() function traverses a directory with File::Find,
+which returns files in readdir() order. This order is nondeterministic
+and depends on the file system.
+
+The lists are used, among other things, to find C files to compile
+(in process_support_files()) and later to link (in c_link()).
+The linking order affects the generated binary, essentially rendering
+it nondeterministic and breaking reproducibility.
