[Bug fortran/23074] New: g77-style typeless BOZ constants not implemented

[p dot w dot draper at durham dot ac dot uk]

In g77 you define a typeless BOZ constant that can be assigned to any other
type, using the formats '....'X, '....'Z etc. This allows PARAMETERs to be 
defined like:

      PROGRAM TLBOZ
      DOUBLE PRECISION inf, nan
      PARAMETER ( inf = '7FF0000000000000'Z )
      PARAMETER ( nan = 'FFF8000000000000'X )
      print *, inf, nan
      END

The relevant g77 description is at:
 
  http://gcc.gnu.org/onlinedocs/gcc-3.4.1/g77/Constants.html

This is related to bug 18026.
