Is there a recommendation of a suitable Linux distribution with gcc 4.8, ideally an ISO image or (even better) a virtual appliance for VMware or VirtalBox? My Debian Wheezy machines have only 4.7.2.

Hi Kurt, I have started to look into this, and I need some guidance about how to prioritize my repairs. There are basically 4 categories of warnings from gfortran?s pedantic critique of my packages: 1. Some errant tab characters it doesn?t like, 2. Too many or too few continue statements 3. Horrible (and obsolescent) arithmetic and computed gotos 4. undeclared doubles and dubious

Dear list The deSolve package allows you to specify the model code in C or Fortran. Thanks to the excellent vignette this works fine. However I have not yet managed to use forcing functions in C code.
