Package: wv2
Version: 0.4.0.dfsg-1
User: debian-...@lists.debian.org
Usertags: ftbfs-gcc-4.4
Tags: patch
This package fails to build with GCC 4.4 which has introduced better
checks in the preprocessor. Your code does something like:
#ifdef A
#elif B
#endif
but the #elif is wrong: #elif requires a condition whereas you're
trying to test whether B is defined. You therefore have to use:
#elif defined(B)
You can reproduce this problem with gcc-4.4/g++-4.4 from unstable.
