Okay, I pulled the latest commits and tried again:

Then the expected "undeclared identifier" errors that would arise from a
missing header. I tried compiling --with-ldap with the Make build, and only
got warnings about deprecated declarations -- that build completed.

I tried disabling ldap with the Meson build but I'll spare the details of
what went wrong there in case I did something wrong, so we can take things
one step at a time.
