Some source based distros like Gentoo already enable -D_FORTIFY_SOURCE=2
by default resulting in the following warnings during build:
<command-line>:0:0: warning: "_FORTIFY_SOURCE" redefined
<built-in>: note: this is the location of the previous definition
Please consider the attached patch to get rid of the warnings.
