    I can't seem to get the __attribute__((unused)) variable attribute to
work.  I'm using gcc v2.8.1, and this is the command-line I used to compile, I
have also listed the output from gcc and the file "t.cc".  gcc says it's
ignoring the attribute, then it gives me a warning about the variable not
being used??? [which is what the attribute is supposed to stop]

gcc -W -Wall -Wunused -o t.exe t.cc
--------------------------------------------------
t.cc:1: warning: `unused' attribute ignored
t.cc: In function `int aaaa(int)':
t.cc:2: warning: unused parameter `int a'
------------------------------------------------
int aaaa(int __attribute__((unused)) a)
{
 return 7;
 }

int main()
{
 return 0;
 }
