DEVOPTS=pedantic adds -pedantic to the compiler flags, but misses on some
diagnostics when using clang, and that are only enabled with -Wpedantic
46c0eb5843 ("files-backend.c: fix build error on Solaris", 2018-11-25)
fixes an issue that was visible also with gcc but not clang so correct
that with the hope that in the future CI could be used for early detection
of similar issues
-Wpedantic is only enabled for clang 10 or higher (only available in macOS
with latest Xcode) but this restriction should be relaxed further as more
environments are tested
