Ah hah! I see a problem. In src/FGFDMExec.cpp you initialize all the simplex 
defaults into trim/guess/*, but src/initialization/FGSimplexTrim.cpp is 
trying to load the defaults from trim/solver/*. 

Going on from there, I'm seeing the defaults are bad. The fcs needs to be in a 
0-1 range instead of a 0-100 range, the alpha and beta angles are being 
interpreted as radians (at least in some places) and are entered in degrees. 
Changing that gives me a solver that doesn't move the controls, though. :(

I never looked at James Goppert's original code, though. Not sure what else 
needs to be adjusted.
