As long as the code from FastAC is not changed, and this is clearly
mentioned in LASzip as a library/algorithm used with a specific
license, I don't see any problems. <br>

Are you aware of the legal issue in LASzip which likely contributed to
ESRI developing their own alternative?
LASzip contains code from the FastAC algorithm which allows distribution
but not modification.
The FastAC license is therefor incompatible with the LGPL-2.1+ license
used for LASzip which guarantees the right to modification.

I believed the LGPL only guarantees the right to modification to the source
code that is licenced under LGPL, or am I wrong ? LGPL can (and does) put
constraints on code that uses it, but why/how could it put constraints on code
it uses ?
Similar situation: I can write GPL/LGPL code that works on Windows and links
against Windows system libraries, which don't give right to modification, but
it doesn't invalidate the fact that I chose GPL/LGPL license for my code and
doesn't prevent anyone using it under their terms.

<pre wrap="">
You can't contain code of those Windows libraries in GPL/LGPL-ed library.
Sebastiaan wrote "LASzip contains code from the FastAC", so the issue
is still valid, isn't it?
Best regards,
