As described in
[sanitizer_common] Fix sanitizer_platform_limits_solaris.cpp
compilation (#198158)
https://github.com/llvm/llvm-project/pull/198158
sanitizer_platform_limits_solaris.cpp fails to compile when g++ is
switched to the default Solaris 11.4 compilation environment, XPG7 +
extensions.
This patch, cherry-picked from upstream, fixes this.
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11.
Ok for trunk?
This patch and
rust: Avoid generic PRIVATE etc. identifiers to fix Solaris build
https://gcc.gnu.org/pipermail/gcc-patches/2026-May/716934.html
are the prerequisites for the actual switch of g++. I'll post that
shortly.
