try l.c not l.cc
I have no idea if you are in C++ environment.

$ cat l.c
#include <curses.h>
int main()
{
    wattr_set(stdscr,0,0, 0);
}
$ diff l.c l.cc
$ gcc-3.4 -Wall -std=c99 -W -pedantic -c l.c
$ gcc-3.4 -Wall -std=c++98 -W -pedantic -c l.cc
l.cc: In function `int main()':
l.cc:5: warning: right-hand operand of comma has no effect
