For me it works fine :)

$ gcc -E -x c data
# 1 "data"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "data"
# 1 "today" 1
Today
# 2 "data" 2
# 1 "is" 1
is
# 3 "data" 2
# 1 "monday" 1
Monday
# 4 "data" 2

File 'data' contains the following:

#include "today"
#include "is"
#include "monday"

Btw, the preprocessor output goes to stdout, so the option '-o' is
not needed.
