Benefits:
1. If a header file gets modified, all dependent stuff gets rebuilt.
No need for 'make clean' after each header modification, no more
spurious errors, no more spurious rebuilds.
2. No more errors due to redefined preprocessor, compiler, and linker
FLAGS.
3. Build scripts don't try to build every *.cc file which happen to
lurk in the source directory.
While at it, remove work around for ancient (fixed in 8+ years) glibc/Linux
bug (the kernel and/or libc was initializing FPU into non-IEEE mode, so division
by 0 resulted in SIGFPE instead of NaN).
the global constructor suffix in shared and static objects.
* m4/c++-constructors.m4 (CL_GLOBAL_CONSTRUCTORS): Add test for
the global constructor suffix, define CL_GLOBAL_CONSTRUCTOR_SUFFIX_PIC
and CL_GLOBAL_CONSTRUCTOR_SUFFIX_NOPIC appropriately.
* include/cln/config.h.in: Provide templates to be filled in by
configure.
* include/cln/modules.h (CL_PROVIDE, CL_REQUIRE): Use
CL_GLOBAL_CONSTRUCTOR_SUFFIX_PIC, CL_GLOBAL_CONSTRUCTOR_SUFFIX_NOPIC.
* autoconf/config.{guess,sub}: Update to GNU version 2003-10-07.
* autoconf/ltmain.sh: Update to GNU version 1.4.3.
* autoconf/autoconf: Remove (from now on we assume autoconf is
installed properly on the sytem).
* autoconf/autoconf.m4: Likewise.
* autoconf/autoconf.m4f: Likewise.
* autoconf/acgeneral.m4: Likewise.
* autoconf/acspecific.m4: Likewise.
* autoconf/aclocal.m4: Regenerate.
* autoconf/acinclude.m4: Remove (while moving the macros...)
* m4/gmp.m4: New file (...to here).
* Makefile.devel: Update to new scheme.
* configure.ac: Likewise.
* include/cln/GV_integer.h: Assume template specializations work.
* include/cln/GV_modinteger.h: Likewise.
* include/cln/config.h.in: Likewise, and drop HAVE_BOOL.
* src/base/cl_base_config.h.in: Drop support for obsolete ftime(3).
* src/base/random/cl_random_from.cc: Likewise.
* src/timing/cl_base_config.h.in: Likewise.
