  Hmm.  Even using the -specs= flag and providing it with an empty specs
file doesn't get rid of them all; it seems that the user-supplied specs
file only allows specs to be overridden in the default one, but does not
altogether replace the default specs.  And some of the non-system-dependant
predefines (like __GNUC__) don't seem to come from specs at all, but are
build into the driver.

  Then again, it doesn't seem that the cpp standalone DTRT either:

$ cat test.txt

well HELLO

this has to test what happens to unix and __GNUC__ and __STDC__ and so on.
