Details:
With the attached Makefiles, when running "rm -f inc; make -n", I
get this output. The "sleep" actually runs (despite "-n"), and the "echo"
shows that "n" is missing from MAKEFLAGS.
make -fm2 bar
make[1]: Entering directory 'foo'
touch inc
make[1]: Leaving directory 'foo'
make[1]: Entering directory 'foo'
echo w
w
sleep 1
make[1]: Leaving directory 'foo'
This was tested with the CVS version. It works correctly with 3.81.
The following change seems to fix the problem ("echo wn" and "sleep" is only
printed, not run).
I'm not sure if it was just a typo, or if there are cases where "1" is
actually needed, though it appears this statement was added to undo the
effects of the preceding "define_makeflags" (line ~2023) for the reexec,
whereas in the normal (non-reexec) case, the "define_makeflags (1, 0);" (line
~2278) does it. If so, it seems logical that "0" is the correct parameter
here.

PS: I hope this report goes to the right place. I could not find a link to
report bugs on the Savannah page. I found this via Google and
