string is const char [] ?

[Carlo Wood]

| Here is a real bug in egcs:
| 
| void f(      char *) {}
| voif f(const char *) {}
| 
| f("test not const"); // error in egcs. f(const char *) must be called,
|                      // because the type of string literals now is
|                      // array of n const char. However egcs calls
|                      // f(char*). -Wwrite-strings has no effect.
|                      // And even warning is surpressed.
| 
| Oleg.

Shouldn't this be added as a test in the testsuite?
