Thanks for your help trying to pin down the cause of this issue.

Your build test result inspired me to try another build with
--std=c99 and xwin excluded from the build using the CMake options
-DPLD_xwin=OFF -DPLD_tk=OFF.  And the PLplot build was a complete success for
that case!

So it appears this --std=c99 (but not --std=gnu99) build bug
shows up only if there is an attempt to build the xwin device.

Some of your previous tests on Cygwin have included xwin and some have
not because you had to take some extra steps to allow xwin to be part
of the build.  Did your current build test with --std=c99 include
xwin?

If your successful build with --std=c99 did include xwin, then that is
pretty clear evidence that there is nothing wrong with our xwin code
and my gcc --std=c99 xwin build issue is instead due to my gcc version
which is "gcc (Debian 4.9.2-10) 4.9.2"
