To you regard this as conditio sine qua non for this patch?

By the way, we currently have already some warning problems, e.g.,

   print *, acosh(1.0)

compiles without any warning/error with "gfortran -std=f95" only using
"-std=f95 -Wall" one gets an error.

(See bug report for suggested fix.)

gfortran 4.2 used the user function and gave thus a link-time error if
there was no user function.
