So, if I get this straight, the current status of gfortran on hppa-hpux (4.4
and 4.3) is:
  - gfortran.dg/nint_2.f90 failing everywhere
  - gfortran.dg/integer_exponentiation_2.f90 and
gfortran.dg/parameter_array_init_3.f90 failing only on hppa64-hp-hpux11.11
  - gfortran.dg/include_2.f90, gfortran.dg/integer_exponentiation_4.f90,
gfortran.dg/namelist_42.f90 and gfortran.dg/nan_3.f90 failing only on
hppa1.1-hp-hpux10.20

(There is a gfortran.dg/ldist-1.f90 failure, but it's not specific to
hppa-hpux.)

Now, some analysis:
  -  integer_exponentiation_4.f90 is tracked as PR33584; the failure happens on
GMP, which suggest a miscompiled GMP or MPFR, see my questions there
  - nint_2.f90 is PR33595; I think it is a bug in either the system math
library, or one of libgfortran's fallback libm functions being incorrect
  - integer_exponentiation_2.f90 is PR31832, probably a libm bug (see comment
#1 in that PR)
  - for namelist_42.f90 and nan_3.f90, I see you've opened new PRs, thanks
  - for include_2.f90, I think a simple look at the testsuite log will tell us
what happens.
