webdar compilation issues

Hi Denis,

I wanted to let you know that webdar is failing to compile on Debian sid
(which will eventually become the next release).  Information here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1133665

I discovered that it is the -std=c++14 that is doing this.  The rest of
the system is built to a newer standard.  My workaround is to run this
after configure:

sed -i 's,-std=c++14,,g' Makefile */Makefile

but I bet that others will run into this as their environments move to
newer compilers as well.

Thanks,

John
