Long process names break compile

[jmlorenzi]

Compilation using the otf backend breaks for models with have long process names (\approx 30 characters). This is related, I guess, to the fact that the intermediate source file generated for f2py has even bigger function names. e.g.

subroutine f2pywrap_proclist_parameters_get_rate_co_diffusion_brid&
&ge_bridge_down (get_rate_co_diffusion_bridge_bridge_downf2pywrap, &
&cell)

as it appends f2pywrap and the modules name to the function name.
