[plt-scheme] defmacro (define-macro) and hygienic macros

I have a question about macros in general:

When I look at the documentation for defmacro, I see that a
datum->syntax-object and back again is used, but I was under the
impression that unhygienic macros were just that because they were
lower level or less sophisticated than hygienic macros, which are a
design improvement on macros, making them easier to use and
understand.  Am I on the wrong track here?

I am having problems finding where the definition for define-syntax
is, so cannot see how it is constructed, but maybe it is done in c.
If anyone could point me in the right direction here it would be much
