- The header file layout has been cleaned up, mostly in terms of the

change in newlib and aligns the affected headers more closely to

These changes are leading to lots of errors when building emacs:

This puzzles me. It looks like you're missing sys/types.h when
including sys/signal,h, but sys/signal.h includes sys/types.h by
itself, prior to including cygwin/signal.h.
How can I reproduce this? An STC like this:
#include <signal.h>
main () {}
is definitely not sufficient.
Sorry, I hadn't looked at what was happening closely enough before sending
my mail. The errors occur while compiling some Gnulib modules in the emacs
source tree. It may take me a while to sort this out. Maybe Gnulib will
have to be patched to take Cygwin's new header layout into account.
I'm still puzzled. The changes, especially to sys/signal.h and
cygwin/signal.h are rather minor. The really big thing is to move the
macros related to select(2) from sys/types.h, where they never really
belonged to, into sys/select.h, rather than including sys/types.h from
sys/select.h. Especially the changes to sys/signal.h and cygwin/signal.h
don't really add up to the error messages you encounter. I inspected
the files today and I really don't see how this could happen :(
