in cache.h:

#define LOCAL_REPO_ENV_CAPACITY 20
const char *const l_r_e[];

in environtment.c:

const char *const l_r_e[LOCAL_REPO_ENV_CAPACITY] = { ..., NULL };

and the compiler will croak if the constant becomes too small. (Oh, I
know, you must use the 'inconsistent mode' that I nit-picked if you use
this approach.)
