message(STATUS
"WARNING concerning spurious warning messages generated by the gfortran compiler.
The new Fortran binding is known to generate some ~50 \"marked
PRIVATE\" warning messages when building the plplotfortran target with the
gfortran Fortran compiler. A typical example of such a warning
message is
Warning: Symbol 'interface_plcont' at (1) is marked PRIVATE but has been given the binding label 'c_plcont'
It appears these warnings (which do not occur if using the ifort or
nagfor Fortran compilers) are due to a gfortran bug (see
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49111> and
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64861>), i.e., they
are spurious warnings concerning completely valid use of the
private attribute for interface blocks describing C routines.
There appear to be no known negative consequences of this gfortran
bug other than the spurious warnings themselves. Until this gfortran
bug is fixed, these ~50 \"marked PRIVATE\" warnings should just be
ignored for those using gfortran."
