strcchrnul.c - error: use of undeclared identifier 'NULL'

[tseemann]

This occurs on OSX compiler with both GCC and CLANG:

clang -DHAVE_CONFIG_H -I. -I../src   -I/usr/local/opt/libdivsufsort/include -I/usr/local/Cellar/gsl/1.16/include  -g -O2 -c -o reallocarray.o reallocarray.c
strchrnul.c:7:14: error: use of undeclared identifier 'NULL'
        return p != NULL ? p : strchr(s, '\0');

I'm guessing NULL is defined in stdio.h or stdlib.h and you have no #include in that C file.

That file is never compiled under linux, thus I didn't catch the error. Should be fixed now.
