Thanks. I am verifying it but it looks fine.

One small detail: Please keep the commit comment lines under 80
columns. Not sure if there is any technical reason for this, but it's
our convention.

Were those in the bundled 3rd-party libraries (like icu, nss, etc) or
in LibreOffice's own code? Our own code is supposed to be warning-free
with most current compilers (except a few separately handled places,
where we use #pragmas or options to make warnings non-fatal, or go
away). It is a good idea to configure your build with --enable-werror;
then the -Werror flag will be used when compiling LO's own code, and
any warnings will cause the build to stop.

> code is contributed under the LGPLv3+ / MPL

Ah OK. It might be easiest to give a blanket statement about past and
future contributions instead of remembering to say this with each
change,

Also, nowadays it is easier (we hope) to submit and review/accept
changes through gerrit instead of email. See
https://wiki.documentfoundation.org/Development/gerrit . (I hope that
is the relevant wiki page...)

Cheers,
