FORTRAN COMMON blocks require misaligned accesses to double precision

R E Q U I R E in that it is neither optional nor wise to emulate with

This option is violated by all compilers that I currently have
access to, and is also incompatible with, for exmaple, the x86_64
ABI on Linux (which requires alignment as if for C structs).

For gfortran, you need a special flag to enforce it.
