* Makefile.am: Fixed install-data-local target to use
$(mkinstalldirs) for the installed header files to ensure

* Makefile.in: Regenerated.
* Makefile.am: $(INSTALL), $(INSTALL_DATA), and $(INSTALL_PROGRAM)
can be a relative path to $(top_srcdir)/install.sh so ensure the

Similarly, add AM_MAKEFLAGS to FLAGS_TO_PASS so they also get passed
properly to subdirectories.
* Makefile.in: Regenerated.
* Makefile.in: Regenerate.
* libc/include/_ansi.h (_EXFUN): Define specially for __CYGWIN__.
