Homebrew gcc 14.2.0_1 fixed the issue, and the workaround is no longer
needed. Not only not needed, but the workaround is breaking builds with
the fixed gcc.
Auto-detect the upstream fix and stop applying the local workaround if
detected.

that started advertising the `availability` attribute, which then gets used

by Apple SDK, but, in a way incompatible with gcc, resulting in misc errors

inside SDK headers, e.g.:
|
|
error: attributes should be specified before the declarator in a function
|
|
definition
|
|
error: expected ',' or '}' before
|
|
Followed by missing declarations.
|
|
Work it around by overriding the built-in feature-check macro used by the

headers to enable the problematic attributes. This makes the feature check
|
|
fail. Fixed in 14.2.0_1. Disable the workaround if the fix is detected. */

rely on the old name, and with this inconsistency our builds fail due to

missing declarations. It happens when using mainline llvm older than v18.

Later versions fixed it by predefining these target macros, avoiding the

faulty dynamic detection. gcc is not affected (for now) because it lacks

the necessary dynamic detection features, so the SDK falls back to
