>Description:
When my code snippet is compiled without the -O switch, gcc compiles
the file corectly, and the program runs correctly.
When compiled with the -O switch, gcc complains about conflicting types
for built-in function `fprintf'.
>How-To-Repeat:
Preprocessor output is appended here.
Compiles with: gcc -o try try.c
But not with: gcc -O -o try try.c
When the -O switch is used, gcc converts printf(...) to
fprintf(stdout, ...) which may not always be appropriate.
>Fix:
Do not use -O switch for this code.
