Do we need a new gcc release to go along with the recent ssp changes?

The following commit message seems to answer my question:

     Note that this does require building gcc with --disable-libssp and
     gcc_cv_libc_provides_ssp=yes.

Correct.

Are there plans to coordinate the release of Cygwin 2.10.0 with a new
gcc release?  In the meantime, I guess package maintainers have to build
with -U_FORTIFY_SOURCE in order to test building with Cygwin 2.10.0.  Or
am I missing something?

-D_FORTIFY_SOURCE is not the default, so simply omitting it is
sufficient.

I was talking about building projects in which _FORTIFY_SOURCE is defined by default. That happens, for instance, in the gnulib subdirectory of the emacs tree, so it may affect other projects that use gnulib also.

You could also just delete
/usr/lib/gcc/*-pc-cygwin/6.4.0/include/ssp, since we won't need it
anymore and it wasn't even being used properly in the first place.

That's a simpler workaround than what I was doing.  Thanks.

Ken
