                       Neat, but I still don't like it

I'm not a fan of tail call optimization [1], but still, I didn't quite
realize that gcc (Gnu Compiler Collection) [2] will optimize tail calls if
given the -O2 option (found while reading Hacker News [3]).

Okay, this is something I have to try out:

> [spc]lucy:/tmp>cat >forever.c
> int main(int argc,char *argv[])
> {
>   return main(--argc,argv);
> }
> ^D
> [spc]lucy:/tmp>gcc forever.c
> [spc]lucy:/tmp>./a.out
> Segmentation fault (core dumped)
> [spc]lucy:/tmp>gcc -O2 forever.c
> [spc]lucy:/tmp>./a.out
>       (several minutes go by)
> ^C
> [spc]lucy:/tmp>
>

That's interesting. Not sure how it'll impact any code I write, but still,
it's interesting.
