@Bruno and Paul:
Thank you for fixing the const qualifier warning in lib/gl_openssl.h and
the context of how gettext is treated differently by gcc and clang.
I will make a note on Savannah bug #68042 about which warnings are
considered WONTFIX by gnulib and what we (Octave) could do about it in
future. When I get a chance I'll report it upstream to LLVM.
I am not sure yet how to automatically (re)activate
"-Wno-tautological-constant-out-of-range-compare" when compiling Octave
files that include gnulib header files (base64.h in particular). But I
can add that note to the above bug report, so users can add it to their
personal build settings if they want to eliminate that warning.
Thanks,
Arun
