The check runs the C preprocessor on a test program which does
"#include <tk.h>"; if the preprocessor generates any messages (whether
warnings or errors), the check fails.

To determine why the check failed, look in the config.log file,
starting with the line:

	configure:8133: checking for tk.h

As Tk requires X, any problems with the X headers will usually cause
the tk.h check to fail.

If the tk.h check failed, the version check will fail for same
reasons. Again, see config.log.
