Bug squashed, see commit 0757b4f. It was always there, we were just
lucky until now.
What the inclusion of errno.h did is increase the size of the object
file (due to massive debug info about macros), and thus the size of
temacs, by 1.5KB, and that caused writes to emacs.exe to cross the
page boundary beyond the allocated memory mapping, and segfault.
You can now remove the workaround from stdio-impl.h. (I already did
that in the Emacs repository.)
Thanks.
