-            // First a bit of background. On Windows, the file format is not ELF,

-            // section, ".note.rustc", you'll note is over 8 characters.

-            // On more recent versions of gcc on mingw, apparently the section name
-            // is *not* truncated, but rather stored elsewhere in a separate lookup
-            // table. On older versions of gcc, they apparently always truncated th
-            // section names (at least in some cases). Truncating the section name
-            // actually creates "invalid" objects [1] [2], but only for some
-            // introspection tools, not in terms of whether it can be loaded.

-            // Long story short, passing this flag forces the linker to *not*
-            // truncate section names (so we can find the metadata section after
-            // it's compiled). The real kicker is that rust compiled just fine on
-            // windows for quite a long time *without* this flag, so I have no idea
-            // why it suddenly started failing for liblibc. Regardless, we
