David Edelsohn <dje at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #2 from David Edelsohn <dje at gcc dot gnu.org> --- This has nothing to do with dejagnu. On AIX, collect2 re-invokes the compiler and collect2 uses the compiler command-line arguments. With or without dejagnu, the command is invoking a fortran-specific option *and* invoking the linker wrapped with collect2 to generate an executable.
