Following program fails to link with -std=f95 option, even though dimag() is
supported intrinsic function. It compiles, links fine without -std or with
-std=gnu option.
$ cat dimag.f90
program test_dimag
complex(8) c8
real*8 result
c8 = cmplx(1.e0_8, 0.e0_8)
print *, dimag(c8)
end program test_dimag
$ gfortran -std=f95 dimag.f90
/tmp/cc0aHEPk.o: In function `MAIN__':
dimag.f90:(.text+0x74): undefined reference to `dimag_'
