+/// \brief Compile-time safety check for the -Wl,-wrap=main linker flag.
+///
+/// On Linux, when HPX is statically linked with dynamic main wrapping
+/// enabled, the linker requires -Wl,-wrap=main to intercept main() and
+/// bootstrap the HPX runtime. Without it, programs crash at startup.
+///
+/// This header emits a #warning when those conditions are detected and
+/// the HPX_HAVE_WRAP_MAIN_CONFIGURED define is absent. CMake consumers
+/// get the define injected automatically via the hpx_wrap target's
+/// INTERFACE compile definitions, so they never see this warning.
