dhcp/dhcp-3.0.5-libdhcp4client.patch
David Cantrell 3b727ca6ac - Ensure that Perl and Perl modules are not added as dependencies (#234688) 
- Reorganize patches by feature/bug per packaging guidelines (#225691)
- Move the following files from patches to source files:
    linux.dbus-example, linux, Makefile.dist, dhcp4client.h,
    libdhcp_control.h
- Compile with -fno-strict-aliasing as ISC coding standards generally don't
    agree well with gcc 4.x.x
