kargl at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kargl at gcc dot gnu.org --- Comment #1 from kargl at gcc dot gnu.org 2012-02-22 03:16:04 UTC --- Please define fails. What is the error message you get? All procedure included in gfortran's runtime library are treated as intrinsic procedures unless you use -std= to restrict gfortran to a particular standard. As it is an intrinsic procedure, etime already has an explicit interface. So, trying to re-specify an interface makes no sense.
