Minor fixes in 1998/dlowe

The program (both main and alt versions) had main()'s return type as
void. To make it more portable, like another entry (that I was asked to
make this same change), I changed it to int.

 ## [1998/dlowe](1998/dlowe/dlowe.c) ([README.md](1998/dlowe/README.md]))
 
+Cody made the program more portable by changing the void return type of `main()`
+to be `int` (in both versions).

 Cody added the scripts [try.sh](1998/dlowe/try.sh),
 [pootify.sh](1998/dlowe/pootify.sh) and
