This is a metabug for all issues in gfortran that need to be resolved before gfortran can be used as a complete replacement for g77.
I'm not sure about the following bugs: - PR 15553 : does this also occur without explicit interfaces? IOW is it possible to provoke this error in Fortran 77 code? - PR 18833 : I'm not sure if this is valid Fortran 77 -- Summary: [metabug] g77 features lacking in gfortran Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tobi at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org BugsThisDependsOn: 5900,12884,13082,13257,13939,14067,14994,15234,15235,152 66,15326,15332,15382,15966,16435,16436,16465,16511,16531 ,16580,16907,17229,17285,17423,17472,17675,17737,17871,1 7941,17992,18026,18210,18398,18481,18518,18540,18576,186 00,18714,18737,18781,18794,18827,18870,18879,18977,18982 ,19021,19052,19155,19216,19280 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19292
