If one runs the attached Fortran 2008 program with GCC 4.4 and default options
one gets:
  Error: 'x' argument of 'acos' intrinsic at (1) must be REAL
for the complex arguments, which is OK.

However, using -std=f2003 one gets additionally warnings of the kind:

  r4 = asinh(r4)
       1
Error: Can't convert UNKNOWN to REAL(4) at (1)

Which are completely bogus. (The attached file is a testcase for the complex
acos etc. implementation for PR 33197.)
