Preserves comments in preprocessed output.
>>- -C---------------------------------------------------------><
The -C option has no effect without either the -E or the -P option. With the -E option, comments are written to standard output. With the -P option, comments are written to an output file.
To compile myprogram.c to produce a file myprogram.i that contains the preprocessed program text including comments, enter:
xlc myprogram.c -P -C
