Hi Davide, Hazen, the Fortran bindings for PLplot already have a solution for this problem. I simply forgot about it - most PLplot functions avoid the underscore, so the issue does not arise. As Davide explains, it occurs with a number of compilers, most notably of the GNU lineage.
I will repair this.
