typofixes - https://github.com/vlajos/misspell_fixer

This is an imported file, so Xapian isn't the place to correct any typos in it, but I don't think this a typo anyway - "configury" is being used as a term for "autotools stuff" - e.g. see this section heading in the (rather out of date now) Goat Book: https://www.sourceware.org/autobook/autobook/autobook_167.html

The rest look good from a quick scan - will work through and apply them.
