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. Delete ancient target test. * install-sh: New script. cygserver/ChangeLog: 2012-11-12 Christopher Faylor <me.cygwin2012@cgf.cx> * Makefile.in: Revamp for new configury. * configure.in: Revamp for new configury. * aclocal.m4: Regenerate. * configure: Ditto. * autogen.sh: New script. cygwin/ChangeLog: 2012-11-22 Christopher Faylor <me.cygwin2012@cgf.cx> * select.cc (select): Don't return -1 when we've timed out after looping. 2012-11-22 Christopher Faylor <me.cygwin2012@cgf.cx> * Makefile.in: Revamp for new configury. (datarootdir): Add variable setting. (winver_stamp): Accommodate changes to mkvers.sh setting.

(ps.exe): Don't add useless -lcygwin. (ldh.exe): For consistency, add to existing MINGW_LDFLAGS rather than redefining them. (cygcheck.exe): Always include -lz for MINGW_LDFLAGS.
