configure ok; make failure of octave-2.9.17

[Hans-Jürgen Greif]

Dear David Batemam,

thank you  for your tip.  Today pcre was updated and  I have commented 
out the whole block in regexp.cc:
/*
c#if defined (HAVE_PCRE_PCRE_H)
c#include <pcre/pcre.h>
c#elif defined (HAVE_PCRE_H)
c#include <pcre.h>
c#elif defined (HAVE_REGEX)
c#if defined (__MINGW32__)
c#define __restrict
#endif
#include <regex.h>
#endif
*/
and have set simply

#include <sys/types.h>
#include <regex.h>

and it works.

Best regards,
 gre
