Harald Anlauf <anlauf at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |anlauf at gmx dot de --- Comment #2 from Harald Anlauf <anlauf at gmx dot de> --- gfortran is quite in line with other compilers. ifort is also quiet by default. However, % gfc-trunk prxxx.f90 -std=f2008 prxxx.f90:4.13: write (*,*), 1, 2, 3 1 Error: GNU Extension: Comma before i/o item list at (1) % ifort prxxx.f90 -stand f08 prxxx.f90(4): warning #5198: Use of comma to separate io-access spec and io_list is non_standard. write (*,*), 1, 2, 3 -------------^ So gfortran is even stricter than ifort. Did you complain to Intel?
