    GCC also has some limited support for traditional (pre-ISO) C with
    the `-traditional' option.  This support may be of use for
    compiling some very old programs that have not been updated to ISO
    C, but should not be used for new programs.  It will not work with
    some modern C libraries such as the GNU C library.

[...]

    You cannot use `-traditional' if you include any header files that
    rely on ANSI C features.  Some vendors are starting to ship
    systems with ANSI C header files and you cannot use `-traditional'
    on such systems to compile files that include any system headers.

I suspect you'll have to port the program to modern C.  I'd start by
losing "-traditional -ansi" and seeing where the compiler stops first.

I'm not sure why you think you need the -msoft-float option, reading
the documentation for it seems to imply that it won't even work
without getting some additional libraries.  (But you may have some
reason for using it that I'm not aware of.)
