- added support for externally built modules,
- improved support for in-tree shared modules,
- fixed diversion bugs,
- configure displays some informative messages,
- faster static build
(libtool isn't used anymore for compiling non-PIC objects),
- dependencies comparable to automake's without requiring GNU make or GCC,
- working make clean for non-GNU makes.
necessary, because we can change the value of INCLUDES globally in one
place (configure.in).
Also add two defines in thread-safe mode
(_REENTRANT and POSIX_PTHREAD_SEMANTICS)
with libtool components
* SAPI targets can enable thread-safe mode and define
shared/static/program build target
* all configure scripts use the same config.cache
* phplibdir is $(top_builddir)/modules to avoid
permission problems
* sapi/*/Makefile.inc are gone
* runpath handling cleaned up
* top-level Makefile.in obsoleted through Makefile.am
* --enable-versioning uses libtool's cleaner and more
portable -export-symbols feature
