Issue is really in vxl.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
More information and reason for this action is here:
yselkowitz's DiffusionKurtosisFit-0.1.1-3.fc25 completed http://koji.fedoraproject.org/koji/buildinfo?buildID=742815
Fixed for now by building with -std=gnu++98.
