[avr-libc-dev] Is the Caldera license acceptable?

[Joerg Wunsch]

While trying to add floating point conversions to vfprintf(), i
contemplate using the V7 UNIX approach, which uses ecvt(), fcvt(),
and gcvt() to convert the numbers.  For some reasons, this
currently looks more promising to me than dtostre()/dtostrf()
(in particular, since these functions already implement array
boundary checks to not overflow the resulting string).

Since old Unices are now opensource, we could use the original
implementation directly.  However, the Caldera license that made
these Unices opensource is basically the old 4-clause BSD-style
license, i. e. it contains the clause with ``All advertising
materials...'' which GNU folks seem to hate.  So the question is,
would this be a problem to us (including hosting it on savannah),
or could we use that code literally?

The original Caldera document can be found e. g. at
ftp://minnie.tuhs.org/UnixArchive/Caldera-license.pdf.  I'm
appending a text translation of it for reference.
