OK, I figured the main problem here - the Makefile specifies '-ansi'.
Removing it fixes the simple problems.

strnlen(), memmem() and memrchr() need "#define _GNU_SOURCE"
for <string.h> which is probably missing.

The reference to __wrap_alloca() is really unprototyped and
mf-runtime.c needs fixing.
