(3) would confuse linking C code and Fortran code together, which might 
even break g77 as much of the runtime library is written in C.  I don't 
think this is a good option.

The size is selectable apparently because you will get poor performance 
with 32-bit floats, because the FPU requires mode-switching which is 
currently not implemented.  So it might make sense to leave the 
selectable size support in, and just change the default.
