This was true of earlier versions of make (originally PMake), which
supported cpp-like #if, #undef, #include, etc. directives.
You can still find some traces in the source. For example, in parse.c,
Parse_File(), see the logic preceding the lines
if (*line == '#') {
/* If we're this far, the line must be a comment. */
goto nextLine;
}
Incidentally, /usr/share/doc/psd/12.make documents the '#' rather than
the '.' forms.
