--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Another WONTFIX?

Note that the GCC documentation

-Wfloat-conversion
Warn for implicit conversions that reduce the precision of a real value. This
includes conversions from real to integer, and from higher precision real to
lower precision real values. This option is also enabled by -Wconversion. 

should mention that the command line option '-Wfloat-conversion' is valid for
C/C++/ObjC/ObjC++ but not for Fortran.
