More or less: the symlink is to Versions/Current/Headers.

I've checked: the original invocation is
/private/var/gcc/regression/master/14-gcc/build/gcc/xgcc
-B/private/var/gcc/regression/master/14-gcc/build/gcc/
/vol/gcc/src/hg/master/darwin/gcc/testsuite/gcc.dg/framework-1.c
-fdiagnostics-plain-output -F. -S -o framework-1.s
with cc1 called like
/private/var/gcc/regression/master/14-gcc/build/gcc/cc1 -quiet -v -F. -iprefix
/private/var/gcc/regression/master/14-gcc/build/gcc/../lib/gcc/x86_64-apple-darwin23.3.0/14.0.1/
-isystem /private/var/gcc/regression/master/14-gcc/build/gcc/include -isystem
/private/var/gcc/regression/master/14-gcc/build/gcc/include-fixed -D__DYNAMIC__
/vol/gcc/src/hg/master/darwin/gcc/testsuite/gcc.dg/framework-1.c -fPIC -quiet
-dumpbase framework-1.c -dumpbase-ext .c -mmacosx-version-min=14.0.0
-mtune=core2 -version -fdiagnostics-color=never -fno-diagnostics-show-caret
-fno-diagnostics-show-line-numbers -fdiagnostics-urls=never
-fdiagnostics-path-format=separate-events -fdiagnostics-text-art-charset=none
-o framework-1.s
After the usual messages about nonexistant directories, we get to
#include <...> search starts here:
.
/private/var/gcc/regression/master/14-gcc/build/gcc/include
/private/var/gcc/regression/master/14-gcc/build/gcc/include-fixed
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks
End of search list.
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Headers/string.h
has
#include <machine/trap.h>
which lives in
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/machine/trap.h
Given the above search list, "machine/trap.h" should work, but
<machine/trap.h> doesn't.
When using the bundled clang, I get
$ clang /vol/gcc/src/hg/master/darwin/gcc/testsuite/gcc.dg/framework-1.c -F. -S
-o framework-1.s
