* eoRNG.cpp, eoRNG.h (K, M, N): Declare static and initialize in cpp.
* t-eoGenOp.cpp (init): Do not add std::ends to end of string, as this
results in escape-codes (^@) to be printed at runtime and is not
necessary anyway.
* test/t-eoSymreg.cpp (SymregNode::operator()): Initialize r1 and r2 to
avoid compiler warnings.
