* Strictly speaking, this will lead to invalid C when

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