Well, fortran added -fcheck=... options with r0-92144, and d's lang.opt was 
added with r9-3689.  So gfortran was clearly first.

Does the Alias processing take into account the language?  I could not figure 
this out.

(I would naively expect that this happens for each language separately, as one 
could mix e.g. fortran and c source files on the gfortran command line).
