! For GCN offloading compilation, when gang-privatizing 'dt_parm.N'
! (see below), we run into an 'gang-private data-share memory exhausted'
! error: the default '-mgang-private-size' is too small.  Per
! 'gcc/fortran/trans-io.cc'/'libgfortran/io/io.h', that one is
! 'struct st_parameter_dt', which indeed is rather big.  Instead of
! working out its exact size (which may vary per GCC configuration),
! raise '-mgang-private-size' to an arbitrary high value.

! It's only with Tcl 8.5 (released in 2007) that "the variable 'varName'
! passed to 'incr' may be unset, and in that case, it will be set to [...]",
! so to maintain compatibility with earlier Tcl releases, we manually
! initialize counter variables:
! { dg-line l_dummy[variable c_compute 0] }
! { dg-message dummy {} { target iN-VAl-Id } l_dummy } to avoid
! "WARNING: dg-line var l_dummy defined, but not used".
