[M3devel] unicode in libm3 or separate package

Huh? No they aren't.

bootstrapping uses old compiler to build everything after m3core/libm3 (up to cm3)
bootstrapping uses old compiler to m3front/m3back/m3quake/m3linker/cm3/sysutils, but not m3core/libm3.
Then bootstrapping uses new compiler to build everything.

m3core/libm3 can depend on new compiler.
m3front/m3back/m3quake/m3linker/cm3/sysutils cannot (except by more than one step, then they can -- "flexibility via multiple changes")

notice where m3core/libm3 appear.

which I don't use but is possibly clearer to people and what I use was based on it (I missed that upgrade.sh actually builds everything and mine stops at cm3).

This is not necessary, but it is ok.

m3core and libm3 are never built with an older compiler and can depend on a newer compiler.
