yyrealloc is implemended using realloc() and realloc() is defined in #include <unistd.h>

Running deheader (http://www.catb.org/esr/deheader/) towards the generated files from flex, reports
realloc() portability requires <unistd.h>

Plase include in the generated files
#include <unistd.h>
except there is a reason not to do so.
