However, it is better to ask such questions at the mailing list - either gcc-help@ or fortran@ - than in a bug report. See http://gcc.gnu.org/lists.html for more information about GCC's lists. Note: g77 is no longer supported, it has been replaced since 6 years by "gfortran", which is a complete rewrite, which still supports Fortran 77 inclusive many vendor extensions (but which also supports Fortran 90 to (with restrictions) Fortran 2008). In particular, the Windows support (both MinGW and Cygwin, including 64bit Windows) of gfortran is much better than of g77. Thus, I would strongly suggest to update to gfortran. For binaries, see http://gcc.gnu.org/wiki/GFortranBinaries , which links to the official MinGW and Cygwin builds but also to other GCC builds.
