newbi question on AC_CHECK_FILE Warning message (...cross compiling)

[Andrej Aderhold]

Hello,

I got the following line in my configure.in

AC_CHECK_FILE("/etc/ntp.conf", NTP_CONF="/etc/ntp.conf", AC_MSG_WARN([ *** 
/etc/ntp.conf does not exist.]))

when I run autoconf I get the following warning. I get this warning on
each AC_CHECK_FILE macro.

configure.in:79: warning: Cannot check for file existence when cross compiling

I don't have any options set. The configure script also works fine,
but I just want to have this warning disappear. What shall I do ?
thanks
