I installed the attached patch into the Emacs master, to try to work around this problem by putting GCC into C11 mode. Please give it a try.No, that didn't fix it.
Can you investigate why not? The patch should cause 'configure' to put -stdc=gnu11 into CFLAGS. If you look at config.log, it should have something like this:
configure:5924: checking for gcc option to enable C11 features ... configure:6146: result: -std=gnu11 If this isn't the result, what is the result and why?
What about an ad hoc temporary solution that simply defines __ISO_C_VISIBLE to be 2011 on Cygwin prior to the inclusion of <stdlib.h>?
I'd rather not go that route, as __ISO_C_VISIBLE is supposed to be private. I installed the attached patch instead; please give it a try.
