Summary

0000106: configure script sets HAVE_PCAP even if wpcap.dll is missing

Description

On Windows, OMNeT++ ships with a pcap.lib (in msys/lib). However, pcap.lib depends on wpcap.dll which is NOT contained in OMNeT++, but needs to be installed separately as part of WinPCAP.

The problem is that the configure script detects pcap.lib, and thus adds -DHAVE_PCAP to CFLAGS (and -lpcap to LDFLAGS). That is, any program that contains #ifdef HAVE_PCAP blocks (e.g. INET Framework!!!) will compile automatically with PCAP support, however it will fail to run because the wpcap.dll is missing.

Fix: configure should check if it can actually *run* a program that links with pcap, and only set HAVE_PCAP if it was successful.
