Hi,

gfortran is way too noisy for zero-length character strings.
I get:

% gfc gfcbug71.f90
gfcbug71.f90:3.44:

  character(len=*), parameter :: prefix = ""
                                           1
Warning: CHARACTER variable has zero length at (1)
gfcbug71.f90:7.14:

  use gfcbug71
             1
Warning: CHARACTER variable has zero length at (1)
% cat gfcbug71.f90
module gfcbug71
  implicit none
  character(len=*), parameter :: prefix = ""
end module gfcbug71

program test
  use gfcbug71
  implicit none
  print *, "prefix = ", prefix
end program test


The first warning is a nuisance, but the second one when USEing
the module is really annoying.  This should not be the default.
