Exactly.  That's why it is called a "minimal" library: it removes
everything that's not really essential for the job, in order to reduce
the code size to a minimum.  The only idea behind that is, if you fail
to use the standard version due to the overall application size being
just over the device's limit, yet you do want printf & friends anyway
(e.g. for some debugging outputs), the minimal version might be the
one just getting you below the barrier again.

Never trust an operating system you don't have sources for. ;-)
