gmake -C mess up MAKEFLAGS?

[RobinK]

This is rather odd.
I have a directory: /tmp/aa, inside aa I have a makefile like this:
>cat /tmp/aa/makefile
all:
        @echo "Inside aa $(MAKEFLAGS)" ;\
        touch a.txt

Then, All I did was:
>cd /tmp
>gmake -C aa

This is the result:
gmake: Entering directory `/tmp/aa'
Inside aa w
gmake: Leaving directory `/tmp/aa'

Where's that "w" after "Inside aa" came from? Why is it in $(MAKEFLAGS)?
If I just do:
>cd /tmp/aa
>gmake
Then everything is fine, there's no "w" at the end

Can someone tell me what I did wrong? Thx!
