412	Compiler flag -fwrapv is not known to GCC 3.3.5	Christian Kellermann	felix winkelmann	"This breaks the build on OpenBSD. (Yes the compiler is ancient). Which is the recommended gcc version that should be used? OpenBSD has a newer GCC in its ports (4.2.x 4.3.x) so it is no problem if this fact is set in stone (aka the readme) somewhere. Or have I missed it? Removing this flag from the makefile of course fixes the issue.

What I gathered from other sources on the net is that versions above or equal to 4.2.4 work ok with it, while 4.1 versions do have issues.
Then again maybe it is just the linux kernel. Source: https://patchwork.kernel.org/patch/35097/"	defect	closed	major	4.9.0	build system	4.6.x	fixed	compiler flags build system
