Hi Arjen: This is an important point that I think needs more discussion because the new Fortran binding for ephcom very much prevents such issues from happening. There I completely dropped all C code and C headers that helped define the old fortran binding (the ephcom equivalent to PLplot's plstubs.h, sc3d.c, sccont.c, and scstubs.c). Instead, I used the features of the iso_c_binding module to write the interface virtually entirely in Fortran (except for the few cases where iso_c_binding did not have some argument processing feature that I had to write from scratch in C). So if I had omitted something from the Fortran interface.f90 file, there was no leftover C infrastructure that would silently generate a f77 fallback. Instead, the omission would be immediately detected when I attempted to use the missing function. I am pretty sure it should be possible (since argument transformations from single to double or double to single is the only extra requirement) to do the same thing for our new Fortran interface. To make that specific, I think our first goal should be to write an interface.f90 file that contains complete information to handle single or double precision versions of x00f.f90 with no C code required at all to define the interface. If you agree, then once that first goal is achieved (again with plstubs.h, sc3d.c, sccont.c, and scstubs.c removed), we should be able to expand the interface (using a C layer where necessary for processing special kinds of arguments) to handle standard examples that include use of more complicated PLplot arguments.
