"strlcpy.h" was added as well. This way one can omit the old HAVE_STRLCPY which
made life hard. The windows and linux makefiles were adjusted accordingly, but

MIDASSYS to? I checkout MIDAS from cvs into /home/olchansk/daq/midas, build it

We stumbled upon and fixed a "double free" bug in src/ybos.c causing crashes in
