Details:
apt 1.2.31 builds fine with autoconf 2.69. With git master:
| checking for h_errno... configure: error: "not found."
That code is:
dnl HP-UX needs -d_XOPEN_SOURCE_EXTENDED for h_errno
AC_MSG_CHECKING(for h_errno)
AC_EGREP_HEADER(h_errno, netdb.h, [AC_MSG_RESULT(normal)],
[CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE_EXTENDED"
AC_EGREP_HEADER(h_errno, netdb.h,
[AC_MSG_RESULT(needs _XOPEN_SOURCE_EXTENDED)],
[AC_MSG_ERROR("not found.")])
])
Obviously this is horrible, but it's out there.
