use AC_CHECK_DECLS to avoid implicit function definition AC_CHECK_FUNCS is not safe, since implicit function definitions is just a warning. On 64-bit glibc systems where reallocarray is not defined or hidden behind macros that are not set, it gets implicitly defined to return an integer, which is a big problem given that it should return a pointer, and leads to immediate segfaults.
