73 * which will expand to
74 * static const char s[] = ("FOO");
75 * and in valid C, the initializer on the right hand side must
76 * be without the parentheses. But many compilers do accept it
77 * as a language extension and it will allow us to catch mistakes
78 * like:
79 * static const char *msgs[] = {
80 * N_("one")
81 * N_("two"),
82 * N_("three"),
83 * NULL
84 * };
85 * (notice the missing comma on one of the lines) by forcing
86 * a compilation error, because parenthesised ("one") ("two")
87 * will not get silently turned into ("onetwo").
