62 | * Strictly speaking, this will lead to invalid C when | |

65 | * which will expand to | |
66 | * static const char s[] = ("FOO"); | |
67 | * and in valid C, the initializer on the right hand side must | |
68 | * be without the parentheses. But many compilers do accept it | |
69 | * as a language extension and it will allow us to catch mistakes | |

77 | * (notice the missing comma on one of the lines) by forcing | |
78 | * a compilation error, because parenthesised ("one") ("two") | |
79 | * will not get silently turned into ("onetwo"). | |
