Sounds like a more portable fix - or fallback - would be for configure
to try to compile

  #include <whatever socket files are needed>
  int accept(int, struct sockaddr *, AC_SOCKLEN_T *);

with -DAC_SOCKLEN_T=socklen_t, if that fail then -DAC_SOCKLEN_T=int,
if that succeeds then use int instead.

(Actually it must also try void* instead of struct sockaddr *;
HPUX is *different*.  But that differente is harmless.)
