Hello.
Recently I get the following error when I try to build CVS HEAD using a default
configure:
../../../net-snmp/agent/mibgroup/if-mib/ifTable/ifTable_interface.c: In
function '_mfd_ifTable_undo_setup_allocate':
../../../net-snmp/agent/mibgroup/if-mib/ifTable/ifTable_interface.c:1410:
error: invalid lvalue in increment
../../../net-snmp/agent/mibgroup/if-mib/ifTable/ifTable_interface.c: In
function '_mfd_ifTable_undo_setup_release':
../../../net-snmp/agent/mibgroup/if-mib/ifTable/ifTable_interface.c:1489:
error: invalid lvalue in decrement
It seems this is the cast-as-lvalue gcc extension, of which the release notes
for gcc 4.0 (http://gcc.gnu.org/gcc-4.0/changes.html) says:
* The cast-as-lvalue, conditional-expression-as-lvalue and
compound-expression-as-lvalue extensions, which were deprecated in 3.3.4
and 3.4, have been removed.
If I apply the attached path it works for me but I am not certain about the
correctness of the patch.
