Hi All,

I recently made a fresh new Cygwin installation. I asked for the full
installation of the "devel" category to be installed, which resulted
in both gcc and gcc4 to be installed. (BTW, great work with gcc4
package, thanks a lot!!!)

I wonder:

1. Is is safe to remove the old gcc (3.*) packages and replace them by
symlinks to the new gcc4 executables?

2. In this case, which executables should I point the symlink to? For
instance, if I were to replace g77 by a symlink to gfortran, which of
the 4 gfortran executables should I use:

    $ locate gfortran | grep exe
    /bin/gfortran-4.exe
    /bin/i686-pc-cygwin-gfortran-4.exe
    /usr/bin/gfortran-4.exe
    /usr/bin/i686-pc-cygwin-gfortran-4.exe

3. Lastly, just a dumb question: why do we get multiple executables in
the first place? I noticed that g77 also comes in multiple files:
    $ locate g77 | grep exe
    /bin/g77.exe
    /usr/bin/g77.exe

Is that really necessary?

Thanks a lot,
