If they died before with a compile-time error, they still will.

If they died before with a link-time error, they ignored compile-time
warnings (missing prototype), right?  (yes, we went backwards, but not
terribly far)

Manual or automatically generated?  How do get the right #if stuff in
there with something which is automatically generated?

We could replace the manually-maintained support/httpd.exp with a
table that has an optional column for feature test macros which must
be true, then automatically generate an appropriate httpd.exp and


apr_sendfile            APR_HAS_SENDFILE
apr_create_thread       APR_HAS_THREADS

Heck, we could generate Win32's aprlib.def from this too.
