The average C programmer would not have thought to use this extension
unless they just decided one day to try it or they actually read the
gcc documentation (which I know almost nobody does). (We keep getting
bug reports about invalid C++ which explicitly added to the changes
page and in the bug section of the documentation but those people
seems not bothered to read those places.)
if you had the following:
((int*)a)++;
the better idea would be:
char *a1 = (char*)a;
a1 += sizeof(int)/sizeof(char);
a = (typeof(a))(a1);
