If it helps, when building Flightgear, I get compile warnings saying
that there's a narrowing conversion from double to float in some YASim
methods:
|flightgear/src/FDM/YASim/YASim.cxx:261:30: warning: narrowing
conversion of
‘((YASim*)this)->YASim::<anonymous>.FGInterface::get_uBody()’ from
‘double’ to ‘float’ inside { } is ill-formed in C++11 [-Wnarrowing]||
||flightgear/src/FDM/YASim/YASim.cxx:261:43: warning: narrowing
