Wireshark Patching...

Dear All, Please note that after getting the sources using git , I found wireshark directory contains patches ? I did some googling I found that if I need to patch wireshark I should run like the below command : 1. patch -p1 < patch path/name the configure and compile , but while checking wireshark sources I didn't find for packet-gsm_abis_oml.c in the path of wireshark /epan/dissectors? does the patch abis_oml.patch(available under wireshark directory with the delivery downloaded with git) create it ? Thanks, Omar Atia
