--- Comment #9 from Mikael Pettersson <mikpelinux at gmail dot com> --- Created attachment 49925 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49925&action=edit ensure fileno_unlocked() is visible on Cygwin Kludge to work around configure breakage. Not pretty, but at least it lets bootstrap w/ Ada succeed on Cygwin.
