Hi Michael,

I missed an example about these functions.

POSIX requires that the <regex.h> header shall define
the structures and symbolic constants used by the
regcomp(),  regexec(), regerror(), and regfree() functions.

Therefore, there should be no need to include <sys/types.h> at all.

The POSIX docs don't use that include:
