That "warning" showed up with some recent version of meson. It's harmless--more of a suggestion than a 
warning!

Balsa has always limited "-Werror" to builds from the git tree, so that other builds (e.g. from tarballs) can show a 
compiler warning without aborting the build. The only way I know to achieve that is to add "-Werror" to the compiler 
flags when building from a git tree.

Meson allows "werror=true" in the default_options of the project() function, but that is then unconditional. 
It can be overridden when building an executable target, and we could do that to turn off some errors in non-git 
builds. But much of Balsa's code is compiled into static libraries, and Meson has no corresponding override mechanism 
for libraries.

Best,
