------- Additional Comments From tobi at gcc dot gnu dot org 2005-03-03 22:06 ------- I agree with you that -ff2c should imply -fsecond-underscore. I don't agree that the advantages of -ff2c outweigh the disadvantages of -fno-f2c so far that -fno-f2c should be the default. If we don't switch to -fno-f2c as default now, it will never happen in the foreseeable future.
One practical problem with gfortran and -ff2c is the following: gfortran's library uses the -fno-f2c calling convention, so using -ff2c with my patch so-far will break use of complex functions as actual arguments. The restriction from the quote from g77's documentation applies the exactly opposite way. I haven't yet looked into how much of an effort fixing this would be. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20178
