dnl AIX "xlc -E" and "cc -E" omit #line directives for header
dnl files that contain only a #include of other header files and
dnl no non-comment tokens of their own. This leads to a failure
dnl to detect the absolute name of <dirent.h>, <signal.h>,
dnl <poll.h> and others. The workaround is to force preservation
dnl of comments through option -C. This ensures all necessary
dnl #line directives are present. GCC supports option -C as well.
