Re: [Cin] arm/termux series (possibly broken on x86)

If you are modifying configure.ac anyway, I suggest to comment out the line about "no-unknown-warning-option" ? It causes no end of useless warnings. Also, the detection of the number of cpus (about line 143) is done by a very specific Linux method /proc/cpuinfo) , which does not work on FreeBSD and macOS. It would probably be better to replace it with "nproc", which can be made available on FreeBSD via an alias, and on macOS after installing some stuff with the "HomeBrew" package manager. MatN
