Per http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gfortran/GNU-Fortran-and-G77.html#GNU-Fortran-and-G77 [Gfrortran] is an entirely new program that has been designed to ..., as well as providing backwards compatibility for Fortran 77 An example of legacy fortran 77 support would be "fno-sign-zero does not print the negative sign of zero values for compatibility with F77" A slightly different test: program main val = 0.0 test = sign(0.5, val) - sign(0.5, -val) write (*,*) 'With val = ', val, ' test = ', test if (test .eq. 1) then write(*,*) 'fail' elseif (test .eq. 0) then write(*,*) 'pass' endif stop end gfortran -std=legacy fsign.f ./a.out With val = 0.0000000 test = 1.00000000 fail I'm not sure that -std=legacy would be the best way to implement this, but it would work for me. -- twscofi at sandia dot gov changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |twscofi at sandia dot gov http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40675
