--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Configuring GCC with --disable-libstdcxx-verbose will remove the use of write
in that file, which you should do if running on some non-POSIX embedded system
(you haven't provided any of the information requested by
https://gcc.gnu.org/bugs/ so it's impossible to know what you're doing).
