If I choose not to enable native-compile, why does configure complain so much?

If I choose not to enable native-compile, why does configure complain so much?

Hi,

When I compile Emacs for macOS, I disable native-compilation for good:

./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig \
            LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include" \
            CC=clang OBJC=clang CFLAGS="-g -O3"
            --with-ns --with-modules --with-jansson \
            --with-native-compilation=no

I know what I’m doing and I don’t know why I get all these messages:

checking for gcc_jit_context_acquire in -lgccjit... no
configure: WARNING: Elisp native compiler can't be enabled as libgccjit was not
found.
Please try installing libgccjit or a similar package if you want to have it
enabled.
checking for libgccjit.h... no
configure: WARNING: Elisp native compiler can't be enabled as libgccjit header files
were not found.
Please try installing libgccjit-dev or a similar package if you want to have it
enabled.

I really DO NOT want notice compilation here…and I know that I’m doing.

Just a bit bored by unwanted messages…

Maybe you missed an "\"?

Hello Pedro,

no need to be frustrated, this is just a bug :)

Could you please report it as a bug so we can track it [1]? (emacs-devel
is not used for bugs)

Thanks

Are we sure there's a bug?  My reading of configure.ac is that the
libgccjit test is only done if the value of with_native-compilation is
"default", but not if it is "no".  So I suspect some cockpit error;
perhaps the command was typed incorrectly?
