Well, I figured out why. This was a bug in Twisted's setup.py, which
has a function _check_header that is supposed to invoke the compiler on
a tiny test module to make sure the module being built will build
The new compiler is constructed with new_compiler(), but no arguments
were passed to it; it was this invocation that fails with the error
message I was getting. This bug was introduced some time ago; I'm not
sure why I didn't see it before now.
Using self.compiler instead worked (there's no need to call
new_compiler() when it's already been done for you).
