Problem compiling WRF-4.2 using pgfortran

[bartbrashers]

In phys/module_mp_SBM_polar_radar.f90, there's a call to derf() aka DErF() on line 1528.

https://gcc.gnu.org/onlinedocs/gcc-3.4.6/g77/DErF-Intrinsic.html calls this an "Archaic form of ERF() that is specific to one type for X".

Changing derf to erf makes it compile under pgf90 19.10-0.

Thanks for finding this! I'll submit a pull request to get this fixed for the next bug release.
