Package: thunderbird
Version: 1.5.0.4-2
Your package fails to build with recent versions of the gcc-snapshot
package, i.e. a pre-release of GCC 4.2. The problem is that external
variables are defined both in a C and C++ context, as you can see in
this simple example:
42059:[EMAIL PROTECTED]: ~] /usr/lib/gcc-snapshot/bin/g++ -c t.cc
t.cc:1: error: previous declaration of 'int i' with 'C++' linkage
t.cc:4: error: conflicts with new declaration with 'C' linkage
42060:[EMAIL PROTECTED]: ~] cat t.cc
extern int i;
extern "C" {
extern int i;
}
According to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27227#c8 this is
not valid, so please investgate.
