[Debian-med-packaging] Bug#778165: vxl: ftbfs with GCC-5

[Andreas Tille]

Hi Brett,

thanks for the patch which is for sure helpful.  However, the strange
build problem with missing libc.h was reported at
debian-mentors at .l.d.o[1] but no answer so far. I have no idea how to
cope with this unfortunately. :-(

Thanks for your help in any case

    Andreas.
