Nearly direct copy of a word count program from KNR C, mimicked here only so that I could compare the size of the resulting binary once compiled to my own solution, archived as ex1_10-5.c (ex1-10.5). The resulting binary, as compiled with GCC, was 136 lines long, 2 lines shorter than my own. Challenge failed :sigh:. Good exercise, though; I'll come back to this and study why later.
