--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Quoting round_4.f90, which somehow no one seems to read ...
! Test whether I/O rounding works. Uses internally (libgfortran) strtod
! for the conversion - and sets the CPU rounding mode accordingly.
!
! If it doesn't work on your system, please check whether strtod handles
! rounding and whether your system is supported in libgfortran/config/fpu*.c
!
! Please only add ... run { target { ! { triplets } } } if it is unfixable
! on your target - and a note why (strtod doesn't handle it, no rounding
! support, etc.)
Thus, one way forward would be to exclude the target (Solaris, FreeBSD) - or to
simply add XFAIL as it also only works with very recent GLIBCs.
Alternatively, one could also think about a different technique for handling
the rounding (on input) in libgfortran.
