problem with "silent include" and special target ".DEFAULT"

[Helmut Dipper]

Hello,

make version 3.78.1 (sparc-sun-solaris2.7)
         and 3.79.1 (mips-sgi-irix6.2)
         and 3.79.1 (i686-pc-cygwin)

Consider the makefile:
#------------------------------------------
-include aaa
sinclude bbb

.DEFAULT:
        @echo "target: $@"

#------------------------------------------
and the results:
target: bbb
target: aaa
gmake: *** No targets.  Stop.

How can it be avoided that the rule with the
special target .DEFAULT is applied when trying
to remade not existent include-files?
Must "empty rules" be specified for each include-
file which may exist or not?

Best regards
Helmut Dipper
