Hello

I just compiled current master with '--with-precision=single', '--with-scalar-type=complex', '--with-64-bit-indices',

configure and make work, but 'make check' throws some warnings regarding src/snes/examples/tutorials/ex5f.F90, see below.

mpifort —version says GNU Fortran (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609

I'm not much into Fortran - can you see what's going wrong?
