After hanging long time with older Ubuntu (v.12) I'm updating to v.16 and am very confused with mentions of "gcc-multilib".
Is this actually Apple's "fat binaries" or "universal binaries" model ported to Linux?
That is, have native C libraries on Ubuntu become containers that pack several binaries for various architectures?
If so, we no longer have to specially install 32-bit runtime libs on a x64 system? The "default" package of gcc or g++ libraries contains all needed to run and build 32-bit apps?
