Hi FX,
I'll look at this.
Looking at your patch, I have identified one
compile-time hog in complex_pow_ui:
$ time gfortran complex.f90
real 3m35.506s
user 3m35.329s
sys 0m0.156s
$ cat complex.f90
program main
print *,(1.0, 0.0)**(2**30)
end program main
We should use the same algorithm as in the library
(in pow.m4).
