Fix false ***buffer overflow*** detection
The compiling option __FORTIFY_SOURCE=2 introduced a false ***buffer overflow*** detection when the flexible array 'pattern' was initilized in globset. The compiler is only complaining when the array is in a struct that is in a struct like struct { ...; struct { ...; char name[1]; }} To avoid these false detections, it is enougth to ellipsese the dimension of the array. Seems to be the now standard way of declaring flexible arrays when it was before an extension. So now: struct { ...; struct { ...; char name[]; }} works even when __FORTIFY_SOURCE=2.
