Package: vrweb_1.5-17
Usertags: ftbfs-gcc-4.3

Your package fails to build with GCC 4.3.  Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning.

Error 1)  GCC 4.3 has converted a number of warnings into errors.
With GCC 4.3, you're no longer to just redefine a previous #define.
You need to either avoid redefinitions directly or to use #ifndef to
make sure that something has not been defined already.  See
http://www.cyrius.com/journal/gcc/gcc-4.3-pedwarn.html

Error 2) GCC 4.3 has converted a number of warnings into errors.
With GCC 4.3, you're no longer allowed to put spurious text after
preprocessor directives, such as #else and #endif.  See
http://www.cyrius.com/journal/gcc/gcc-4.3-pedwarn.html

You can reproduce this problem with gcc-snapshot from unstable.  Note
that Red Hat, Novell and Ubuntu have done some work getting packages
to build with GCC 4.3 so there might be patches floating around
somewhere.  I suggest you talk to your upstream.

The vrweb package has been removed from Debian so we are closing
the bugs that were still opened against it.

For more information about this package's removal, read
http://bugs.debian.org/410621 . That bug might give the reasons why
this package was removed, and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.

Kind regards,
