Thanks for the report. But please note the bug is completely harmless from
our POV so I will not be fixing it.

This bit of Makefile affects creation of the file `macro_list' which is used
in the fixincludes process. And seeing as we disable fixincludes.. there is
nil effect on the installed compiler.
