Hello, here is an update on the FORTRAN 77 issue: The proposed solution (a compiler directive) does not work with the current gfortran compiler (issue http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47030).
I can think of several workarounds: - Expand the argument list of plcon1 with the array tr This breaks existing code though - Use a separate subroutine to fill the array in the COMMON block - Use a MODULE despite the fact that we are talking about FORTRAN 77 - all maintained Fortran compilers that I know of are at least conforming to the Fortran 90 standard that introduced modules. - Put the implementation of plcon1 in the same - static - library as plparseopts (which had a very similar issue) The second solution is probably the easiest for us developers, the last the most convenient for us users.
