For the:
-#if (defined(__GNUC__) && !defined(__clang__) && __GNUC__ >= 11) || \
- (defined(__clang__) && __clang_major__ >= 15)
+#ifdef __cpp_lib_source_location
My understanding is that __cpp_lib_source_location is guaranteed
to potentially become defined basically only 2 ways:
A) inclusion of <source_location>
B) inclusion of <version>
Clearly (A) is not the case here and would require a
__has_include(<source_location>) test to allow this style
of attempting to get a definition for
__cpp_lib_source_location .
I looked a round some and did not notice an example of (B),
but I may have missed it.
So, it might be that this changed turned off use of
<source_location> in unintended places.
