ChangeLog: 2012-11-12 Christopher Faylor <me.cygwin2012@cgf.cx> * Makefile.common: Revamp for new configury. Add default compilation targets, include .E processing. Add magic for allowing "CFLAGS" to control optimization options in "CXXFLAGS". * configure.cygwin: New include for Cygwin configure.in's. * acinclude.m4: Delete old definitions. Implement AC_WINDOWS_HEADERS, AC_WINDOWS_LIBS, AC_CYGWIN_INCLUDES, target_builddir, winsup_srcdir. * aclocal.m4: Regenerate. * autogen.sh: New file. * ccwrap: New script. * c++wrap: New script. * config.guess: New script. * config.sub: New script. * configure: Regenerate. * configure.in: Eliminate LIB_AC_PROG_* calls in favor of standard.

Cygwin: Remove ccwrap ccwrap massages the compiler's standard include directories to remove '/usr/include/w32api', with the intent of allowing it to be overriden by '--with-windows-headers' (See 4c36016b). I'm not 100% convinced that this is always working as desired, since in some places w32api includes are done using <w32api/something.h>, which will find them via the path /usr/include. If this does turn out to be needed, this could also be implemented by constructing the appropriate compiler flags once, rather than on every compiler invocation.
