When any hip header included with -D__HIPCC_RTC__, it means that compiler was launched with -E -P to produce a preprocessed header. In this case not a single libstdc++ header can be used, otherwise it causes function redefinition on next attempt to include the same header elsewhere.

stdlibc++ of GCC-15 adds __glibcxx_assert in std::clamp, std::array, etc,
|
|
which breaks HIP code. However, `clang -x hip` autoloads few files,
|
|
one of them is <hip/hip_version.h> (the only one from dev-util/hip),
|
|
where we can undefine __glibcxx_assert until it is fixed in stdlibc++.
