 2. This is ugly, prepare yourself. OS X has a weird problem with how the "TAILQ_END(head)" is used, causing a linking error. Just replace all use of the "TAILQ_END(head)" macro with "NULL".
 
 3. Apply "add mac-arc4random-buf.patch", which removes some bad OS X compatibility code. This will allow libevent to compile on all supported versions of OS X.
 
 4. Apply "openbsd-no-arc4random_addrandom.patch", which fixes the build on OpenBSD (which doesnt provide arc4random_addrandom anymore, see #931354)
 
 5. Apply "libevent-use-non-deprecated-syscalls.patch", which fixes the build on AArch64 architecture (which does not provide deprecated syscalls)
