Hi all,

current WildMagic5 (http://www.geometrictools.com/) libraries, rebuilt
with flags for hardened builds
(https://fedoraproject.org/wiki/Changes/Harden_All_Packages), are:

# checksec --dir /usr/lib64 | grep Wm5
Full RELRO      No canary found   NX enabled    DSO             No
RPATH   No RUNPATH   /usr/lib64/libWm5Applications.so.5.13

Full RELRO      Canary found      NX enabled    DSO             No

Full RELRO      Canary found      NX enabled    DSO             No

Full RELRO      Canary found      NX enabled    DSO             No

RPATH   No RUNPATH   /usr/lib64/libWm5Physics.so.5.13

Samples executable files are tagged with noPIE: http://fpaste.org/285748/

I don't know how to manage the file with "No canary found" supposing
that i have added all flags correctly.
