Hello!
The configure script early checks for net/if.h. Twelve days ago
(2011-03-18) it reported:
checking for net/if.h... yes
checking whether struct tm is in sys/time.h or time.h... time.h
checking for struct tm.tm_zone... yes
checking for struct tm.tm_gmtoff... yes
checking for struct ifreq.ifr_flags... yes
checking for struct ifreq.ifr_hwaddr... no
checking for struct ifreq.ifr_netmask... no
checking for struct ifreq.ifr_broadaddr... yes
checking for struct ifreq.ifr_addr... yes
Now it reports:
checking for net/if.h... no
checking whether struct tm is in sys/time.h or time.h... time.h
checking for struct tm.tm_zone... yes
checking for struct tm.tm_gmtoff... yes
checking for struct ifreq.ifr_flags... no
checking for struct ifreq.ifr_hwaddr... no
checking for struct ifreq.ifr_netmask... no
checking for struct ifreq.ifr_broadaddr... no
checking for struct ifreq.ifr_addr... no
In the list of included C header files I can see a difference:
past now
. /usr/include/unistd.h . /usr/include/unistd.h
.. /usr/include/sys/unistd.h .. /usr/include/sys/unistd.h
.. /usr/include/sys/select.h .. /usr/include/sys/select.h
... /usr/include/sys/_structs.h ... /usr/include/sys/_structs.h
... /usr/include/sys/_select.h ... /usr/include/sys/_select.h
. /usr/include/sys/socket.h
.. /usr/include/machine/_param.h
... /usr/include/ppc/_param.h
. /usr/include/net/if.h . /usr/include/net/if.h
.. /usr/include/net/if_var.h .. /usr/include/net/if_var.h
... /usr/include/sys/time.h ... /usr/include/sys/time.h
.... /usr/include/sys/_structs.h .... /usr/include/sys/_structs.h
.... /usr/include/time.h .... /usr/include/time.h
..... /usr/include/_structs.h ..... /usr/include/_structs.h
...... /usr/include/sys/_structs.h ...... /usr/include/sys/_structs.h
... /usr/include/sys/queue.h ... /usr/include/sys/queue.h
The difference may come from removing these blocks from configure:
for ac_header in sys/socket.h
do :
ac_fn_c_check_header_mongrel "$LINENO" "sys/socket.h"
"ac_cv_header_sys_socket_h" "$ac_includes_default"
if test "x$ac_cv_header_sys_socket_h" = xyes; then :
cat >>confdefs.h <<_ACEOF
#define HAVE_SYS_SOCKET_H 1
_ACEOF
fi
done
for ac_header in net/if.h
do :
ac_fn_c_check_header_compile "$LINENO" "net/if.h"
"ac_cv_header_net_if_h" "$ac_includes_default
#if HAVE_SYS_SOCKET_H
#include <sys/socket.h>
#endif
"
if test "x$ac_cv_header_net_if_h" = xyes; then :
cat >>confdefs.h <<_ACEOF
#define HAVE_NET_IF_H 1
_ACEOF
fi
done
The tests for ifreq.ifr_* show errors like these:
In file included from conftest.c:87:0:
