[NeilB@earthling.net: 2 tests for testsuite]

[Zack Weinberg]

I've added these to the test suite.  Their purpose is to ensure that
future patches don't break cpp -dD or -dM, which is easy to do by
accident.  They only test that the preprocessor doesn't crash; testing
for correct output would require considerable Tcl hackery which I am
not up to (patches welcome).

Zack,

This is it from me.  A couple of tests probably worth adding to the
testsuite.  I haven't bootstrapped so I don't know whether they fail
or not, so I'll leave it to you to apply them.

Neil.
