True, _fcloseall_r, _fscanf_r, _scanf_r and _sscanf_r are already in
cygwin.din.

That's not what was asked...

Ok, here goes again (this time assuming if <function> is exported
_<function>_r may also be exported):

====
for f in $(grep -hoR '_[^ ]\+_r *( *struct \+_reent' .|sed 's, *(.*,,' \
  |sort|uniq) ; do
 grep "^$f" winsup/cygwin/cygwin.din >/dev/null || (
 grep "^$(echo $f|sed 's,^_\(.*\)_r$,\1,')" winsup/cygwin/cygwin.din \
 >/dev/null && echo $f )
done

'_mallopt_r' is still there... Is there any reason it
should not be exported, when 'mallopt' is?

:  involves some research.

And here I was, thinking you were mean...

hth,

Buzz.
