Can the ABIs be unifed?
  line up struct stat, or make thin wrappers? 
  line up errno.h? 
  lineup lseek/fseek flags? (probably already the case)
  use the larger of the two jmpbuf sizes?
  keep FILE* opaque?
    Maybe line up just its size, if stdin/out/err are defined to be
      elements in an array.
  either line up ctype's data, or use real function calls?
  etc.?
  Under a -slightly-slower-but-more-compatible switch?

ABI multiplicity bugs me..

I realize that it might be too late, at least without a "thin translation layer",
and even then. Reasonable for like stat, but not really for errno.h, for example.
