Obviously you didn't put it back together after word wrap broke it up.

gcc -pedantic -Wall -Wcast-qual -Wmissing-prototypes -Wshadow  shuffle.c -
o shuffle 

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]

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.
