You are mistaken: those header lines make the definitions valid when
used with a C++ translator as well as a C translator. 

>The first declare error comes from typedef off_t regoff_t

Insert:
#include <sys/types.h>
before:
#include <regex.h>

and while you're there, correct:
#include <strings.h>
to
#include <string.h>
as the former is non-standard (none of the functions document their
declaration in the former) and merely includes the latter.
