>Description:
When compiling code that explicitly declares a
(const char []) variable named __func__, gcc complains
about being confused by 'earlier' errors, and quits.
Needless to say it does not report any earlier errors.
(see instructions for repeating)

>How-To-Repeat:
Compiling the following code:
    void myfun(void) {
        const char __func__[] = "myfun";
    }
Generates (just) the following diagnostic:
    try.24.c: In function `myfun':
    try.24.c:2: confused by earlier errors, bailing out
>Fix:
One fix is of course not to declare variables named
__func__. There may be others ?
