 Obviously you didn't put it back together after word wrap broke it up.
 gcc -pedantic -Wall -Wcast-qual -Wmissing-prototypes -Wshadow  shuffle.c

 runs with no errors or warnings. If you throw in -std=c99
 gcc -std=c99  shuffle.c -o shuffle shuffle.c: In function ‘main’:
shuffle.c:8:22: warning: implicit declaration of function ‘strdup’; did
you mean ‘strcmp’? [-Wimplicit-function-declaration]

shuffle.c:8:22: warning: initialization of ‘char *’ from ‘int’ makes

 Why? you might ask? ISO C99 doesn't include strdup although it's strange
it pulls strcmp out of its ass.

 gcc -std=gnu99  shuffle.c -o shuffle
 works fine.
