+The Makefile calls awk on a "*.c" glob. The results of this glob are sorted
+but the order depends on the locale settings, particularly whether
+"util.c" and "util2.c" sort before or after each other. In en_US.UTF-8
+they sort one way, in C, they sort the other. The sorting order changes 
+the output binaries. The behaviour also changes dependning on whether
+SHELL (/bin/sh) is dash or bash.
+
+Specify a C locale setting to be deterministic.
