FAIL: gfortran.dg/edit_real_1.f90 on Darwin8

[Jack Howarth]

Dominique,
    Isn't the failure in gfortran.dg/edit_real_1.f90 likely due to
the fact that gfortran (unlike the gcc and g++ compiler) doesn't
generate the $LDBL128 versions of the symbols for function calls
related to long doubles? Reread the threads...

I believe we need to figure out why Andrew's proposed patch
(discussed in that thread) doesn't really work for the gfortran
compiler and the symbols in the gfortran generated object files
lack the expected appended $LDBL128.
