Unused warning

[Eric Lemings]

Greetings,
 
Given the following:
 
[lemings@flame gcc]$ gcc --version

[lemings@flame gcc]$ cat test03.c
 
const char* __attribute__((unused)) s1;
static const char* __attribute__((unused)) s2;
 
[lemings@flame gcc]$ diff test03.c test04.cpp
[lemings@flame gcc]$ make test03.o
gcc -g -Wall   -c -o test03.o test03.c
[lemings@flame gcc]$ make test04.o
g++ -g -Wall     -c -o test04.o test04.cpp
test04.cpp:3: warning: 's2' defined but not used

How do I silence the warning?  The __attribute__((unused)) qualifier
doesn't seem to work.

Thanks,
Eric.
