#     <snip>
#     # 1 "test.c" 2
#     
#     main() { printf("Hello world!\n"); }

# is replaced with
#     # 1 "test.c"
#     #include <stdio.h>
#     main() { printf("Hello world!\n"); }


# Header files whose pathnames contain any of the following patterns
# are considered as standard headers: usr/include, g++-include,
# include/g++, include/c++/<version>, gcc-lib/<anything>/include.
