Oh but the comment suggests that will only be used for tests that
don't use dg-options:
# If a testcase doesn't have special options, use these.
global DEFAULT_FFLAGS
if ![info exists DEFAULT_FFLAGS] then {
set DEFAULT_FFLAGS " -pedantic-errors"
}
I don't know if that's correct, or if the dg-options flags get
appended to these default flags.
You might also need a leading space in the string, like dg.exp uses
(or maybe that's not needed in dg.exp anyway).
