 The automatically added libraries are:
 
 * `FortranRuntime`: Provides most of the Flang runtime library.
-* `FortranDecimal`: Provides operations for decimal numbers.
 
 If the code is C/C++ based and invokes Fortran routines, one can either use Clang
 or Flang as the linker driver.  If Clang is used, it will automatically all
 required runtime libraries needed by C++ (e.g., for STL) to the linker invocation.
