Description Atsushi Nakabayashi 2007-12-04 03:12:42 EST
Description of problem:
snmplib/asn1.c(net-snmp-5.1.2-11.EL4.11) uses SIZEOF_LONG,
but it is not defined. 
And net-snmp.org(net-snmp-5.1.4 or more) defines SIZEOF_LONG 
in include/net-snmp/net-snmp-config.h

Comment 3 Jan Safranek 2007-12-04 09:34:07 EST
I do not see any consequence of the bug. You are right, SIZEOF_LONG is not
defined. But it is used only twice:

1) asn1.c:210
If it is not defined, net-snmp checks integers unnecessarily on 32bit system,
burning few cpu cycles. The result is the same as if SIZEOF_LONG would be defined.

2) asn1.c:1330
Again, if it is not defined, net-snmp checks subidentifier on all architectures,
which is not effective on 32bit system, but has no influence on the result.

Feel free correct me and reopen the bug if I am wrong and you can see some
problems in production. Or contact your Red Hat Support at redhat.com/support,
which is always better than direct Bugzilla report.
