-//! Support for "weak linkage" to symbols on Unix
-//!
-//! Some I/O operations we do in libstd require newer versions of OSes but we
-//! need to maintain binary compatibility with older releases for now. In order
-//! to use the new functionality when available we use this module for
-//! detection.
-//!
-//! One option to use here is weak linkage, but that is unfortunately only
-//! really workable on Linux. Hence, use dlsym to get the symbol value at
-//! runtime. This is also done for compatibility with older versions of glibc,
-//! and to avoid creating dependencies on GLIBC_PRIVATE symbols. It assumes that
-//! we've been dynamically linked to the library the symbol comes from, but that
-//! is currently always the case for things like libpthread/libc.
-//!
-//! A long time ago this used weak linkage for the __pthread_get_minstack
-//! symbol, but that caused Debian to detect an unnecessarily strict versioned
-//! dependency on libc6 (#23628).
