The difference is that the successful compilation/link uses -L to tell
the linker where to look for libgccjit installation:
> conftest.c -lgccjit -lsqlite3 -L/opt/homebrew/Cellar/libgccjit/15.2.0/lib/gcc/current >&5
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
whereas the failing one does not:
> conftest.c -lgccjit -lsqlite3 >&5
> +++ ld: library 'gccjit' not found
> +++ clang: error: linker command failed with exit code 1 (use -v to see invocation)
And the same is true for the compilation command that verifies the
libgccgit.h header can be found: the successful one uses -I to specify
where to find the libgccgit headers:
> -I/opt/homebrew/Cellar/libgccjit/15.2.0/include conftest.c >&5
> +++ configure:28649: $? = 0
> +++ configure:28649: result: yes
The above succeeds due to the -I switch, whereas the below does NOT
use it, and fails:
> -isystem /opt/homebrew/Cellar/pcre2/10.46/include conftest.c >&5
> +++ conftest.c:162:10: fatal error: 'libgccjit.h' file not found
> +++ 162 | #include <libgccjit.h>
> +++ | ^~~~~~~~~~~~~
> +++ 1 error generated.
So in the first case you either told the configure script where to
look for libgccgit or it figured that out by itself, whereas in the
second case you didn't and it couldn't.
Did you use any other configure options besides --with-native-compilation?
if so, which one(s)? And (assuming both invocations were on the same
system), why are the line numbers reported by configure different
between the two cases? This seems to imply that something else
is different between these two builds.

Sorry, I misunderstood you. The situation with dbus is a bit different
because the default in configure.ac is "no", i.e. without specifying
--with-dbus no dbus. AFAIK, only --with-native-compilation has this
"default" handling.

+my 2 cents, it would be great to handle this on macOS so we can avoid
manually specifying configure options.

This is with master on macOS. Haven't checked with emacs-30.
Make sure that libgccjit is installed, for example via Homebrew. In a
terminal, run ./autogen.sh, so that ./configure exists.
1. ./configure
=> libgccjit not found
2. ./configure --with-native-compilation
=> libgccjit is found
I think the reason for this is here:
configure.ac<master>:
5199 if test "${with_native_compilation}" = "default"; then
5200 # Check if libgccjit is available.
5201 AC_CHECK_LIB([gccjit], [gcc_jit_context_acquire],
5202 [], [libgccjit_not_found])
5203 AC_CHECK_HEADERS([libgccjit.h], [], [libgccjit_dev_not_found])
5204 if test "${with_native_compilation}" != "no"; then
5205 # Check if libgccjit really works.
5206 AC_RUN_IFELSE([libgccjit_smoke_test], [], [libgccjit_broken])
5207 fi
5208 fi
I think this misses the special handling of Homebrew and MacPorts
installations of libgccjit that is done a few lines below.
configure.ac<master>:
5218 if test "${opsys}" = "darwin"; then
5219 # Ensure libgccjit installed by Homebrew or macports can be found.
5220 if test -n "$BREW"; then
5221 if test -n "`$BREW --prefix --installed libgccjit 2>/dev/null`"; then
5222 MAC_CFLAGS="-I$(dirname $($BREW ls -v libgccjit | \
5223 grep libgccjit.h))"
5224 MAC_LIBS="-L$(dirname $($BREW ls -v libgccjit \
