Also reorder its call in configure.ac which now allows the PYTHON_VERSION
environment variable to be recognized and processed correctly by the
build system.
Correctly add PYTHON_LIBS (correct ouput variable of AX_PYTHON_DEVEL) to the
Makefile for the Python bindings.
Update README.python for use of PYTHON_VERSION.
Use ax_pkg_swig.m4 from the GNU Autoconf Macro Archive as it is actively
maintained and update configure.ac accordingly.
Moved the Swig test to the bindings section of configure.ac.
Refactored the logic of the Swig test.
Updated ax_python_devel.m4 to latest version in the Autoconf Macro
Archive (removes two email addresses, not other changes).
Removed aclocal-include.m4 and lf_warnings.m4 as they were not being
used any longer.
Update macros definitions in macros/Makefile.am to recent additions and
deletion of the local macro files.
Cleaned up M4sh syntax for variable quoting, replaced shell 'if'
conditionals with M4sh AS_IF macro and shell 'case' with AS_CASE macro.
Properly quoted macro variables. Added comments to configure.ac
describing actions, commented out obsolete macros, commented obsolecent
macros, and added comments for major sections.
Corrected a Mingw linker error on the .EXE files adding
'--enable-auto-import' to their LD flags. Testing this commit on win32
shows that rigctld is now working properly. Will need to port this to
the Stable branch and test.
Replaced older local macros with newer replacements from GNU Autoconf
archive.
