Interesting - can you send a patch to Makefile  to include LC_COLLATE=C
in case it does fixes your problem.

Although LANG=C should IMHO set all LC_XXX settings - so it can be also a bug 
in glibc process ??

What locales are used in your environment ?

Can you attache resulting sorted  cmds.h in your environment ?
