I think it might not be clear from the point of view of a Fortran user (who knows nothing about the compiler actually linking in a library that the user never required).

Perhaps a section "GCC options that most probably won't work for your Fortran code" could be added to the gfortran doc? There, we would explain:

• the reasons why options changing ABI can't be used directly for Fortran programs, even if there's no library involved (because the compiler links in a library)
• a list of common such options
• a hint about the way to work around that if you really need it (ie, building the libraries, including libgfortran, with your ABi-changing option)
