Is there anything I can do to help? Do you need a bug report filed against
newlib?

We can probably do something in os_defines.h like:

#if __cplusplus < 201103L && __STRICT_ANSI__
#undef _GLIBCXX_USE_C99_STDIO
// etc.
#endif

dup of PR 70176 ?

My guess is Cygwin uses a new version of newlib which has stricter C headers
that don't define the C99 functions for __cplusplus < 201103L &&
__STRICT_ANSI__
