I almost succeeded in building a new cm3 from sources now, but I'm
stuck at something again I don't understand. Symbol ___eprintf is
referenced from m3core, but there is no static definition for it in
any library I can find.

 -> linking cm3
generate _m3main.new
compare _m3main.new _m3main.c
rm _m3main.new

Does anybody know what it the standard solution for this?
The symbol is even defined in the dynamic version of m3core itself.
Is static linking not supported anymore? Or should I just link
against one of the above dynamically?
The m3makefile for cm3 still contains

  build_standalone () %-- we don't want to depend on the shared libraries...


Any hint will be appreciated.
