$gcc -std=c99 test.c
test.c: In function 'main':
test.c:6: warning: implicit declaration of function 'strdup'
test.c:6: warning: assignment makes pointer from integer without a cast[code]
What the heck is this, /prog/? Is there some shit around strdup() in c99?

Besides, it's almost always unintentional. You change the behaviour of a function to modify pointed data, not realizing it was meant to be const.
const is not a short form of "constant." A promise not to change something is not a promise that it will never change.
