Why not settle for one master dialect and use awk to translate between dialects?


[Probably because there is a great deal of C code written to comply with
the various versions of the standard, users want error messages that match
the code they wrote rather than some intermediate code, and it would be quite
an awk program that could reconcile all the differences among C flavors. -John]
