Libelektra: compiler warnings

[haraldg]

I submitted a PR for 0.8.21 to openwrt. However there are some compiler warnings - probably easy to fix things like forgotten header files. Please have a look at https://friends.ccbib.org/lambda/build.err

[markus2330]

Thank you for the submission! Can you post a link to the PR for reference?

We'll take a look at the compiler warnings for the next release, I added the Milestone.

[markus2330]

We tried to fix the compiler warnings. The fixes are now in master and will be part of the next release.

Without compiling it for OpenWRT, however, we cannot verify if the warnings are really gone. So please give us feedback about warnings when you compile the next release.

[petermax2]

gcc -Wstringop-truncation (version gcc (GCC) 8.1.1 20180502 (Red Hat 8.1.1-1)) reports several compiler warnings on Fedora 28.

However, I am not sure how relevant these warnings are.
