I haven't tested it, but based on testsuite/gfortran.dg/dg.exp it looks like you could add this in ~/.dejagnurc set DEFAULT_FFLAGS "-funsigned -pedantic-errors" (The -pedantic-errors is what dg.exp uses if the variable doesn't already exist, so this preserves that.) If you're using a site.exp you could add this there instead of ~/.dejagnurc
