Thank you Mike for your quick feedback.

Could there be any compatibility between these licenses ? (perhaps only 
1 way : submit an LO patch on Firebird or submit a Firebird patch on LO)

For example, I think LO can retrieve patches from ApacheOpenOffice but 
the reverse isn't possible (except if all the authors from the patch are 
ok). In the worst case and it would mean, considering 
https://cgit.freedesktop.org/libreoffice/core/commit/?id=45f42681f4d1260c42140a313560534e605f81a4, 
I should ask to Tamas and Lionel (let's put them in cc) if they accept 
to submit the configure part of this patch upstream?
