From 7c905c6c6ca553210ff7dcc2a016e4aaf7d3750c Mon Sep 17 00:00:00 2001 From: des Date: Tue, 6 Jul 2004 15:15:14 +0000 Subject: Fix a number of incorrect assumptions regarding the size of time_t. The code has its own TIME type, which is actually defined to time_t, but it still used u_int32_t in some places. In addition, dhclient not only had two separate global cur_time variables, one of which was defined as u_int32_t and the other as TIME, but cur_time was sometimes shadowed by local variables, leading to widespread confusion as to which of these variable was being referenced. There is a lesson in here somewhere: a decent compiler with warnings enabled should have caught all of this long before it became a problem. This patch has been submitted to the vendor, but it will likely be some time before they release a version that includes it.
