David,
    As for http://code.google.com/p/lilypond/issues/detail?id=3656, the problem 
would appear to be,
from inspection, that flower/include/file-path.hh is included before config.hh 
in file-path.cc.
This prevents HAVE_STL_DATA_METHOD from being set properly for 
flower/include/file-path.hh to use.
