I haven't come across __attribute__ yet. But I did see several warnings telling that strdup() is deprecated and should use the iso c++ conformant name _strdup(). I've ignored it until now because they were just warnings and had no idea how you would feel towards changing it. I think if you change strdup(), strncmp(), etc.. you would be able to compile with -std=c99 (if you can't already).
About variable sized arrays from google-groups comp.lang.c++
[nan at xxx test]$ cat ary.c
[nan at xxx test]$ gcc -pedantic ary.c
ary.c: In function `main':
ary.c:4: warning: ISO C89 forbids variable-size array `array'
Maybe I can mail you libvlc (or a diff or whatever) to see what I changed and if it's acceptable.

I know it was just an example.
