In principle, it is compatible. We do bundle one LGPL 2.1 library (libmbfl).
Having LGPL licensed code may affect downstream users though, e.g. someone
shipping a proprietary version of PHP will be required to build mbstring as
a shared extension, to ensure that the LGPL licensed code portion may be
substituted. For that reason, I don't think we can accept LGPL licensed
code in any required PHP components (that are always statically linked).
Generally, not having LGPL licensed code is strongly preferred.
