------- Comment #2 from burnus at gcc dot gnu dot org  2009-07-22 08:11 -------
The error comes about since with -std=2003, asinh is not an available
intrinsic. Solution for the testcase/attached file: "-fall-intrinsics" or
removal of a(sin,cos,tan)h - which were added only with F2008 though the REAL
version was a GNU extension before.

Current result (4.4, 4.5):

  Error: Can't convert UNKNOWN to REAL(4) at (1)

Expected: A better error message such as gfortran 4.2 had ["Regression"]:

  Error: Function 'asinh' at (1) has no IMPLICIT type

If one enables implicit typing (or explicitly types the function), one gets the
  undefined reference to `asinh_'

And if one uses "abcd", one gets the old 4.2 error. I tried to trace the
problem - with out success so far. At least the function gfc_is_intrinsic seems
to work.
