[Plplot-cvs] CVS update notice (plplot)

[Rafael L. <rla...@us...>]

Update of /cvsroot/plplot/plplot
In directory sc8-pr-cvs1:/tmp/cvs-serv30056

Modified Files:
	sysloc.in configure.ac 
Log Message:
In sysloc.in, changed the list of directories to search for Python headers
(when setting the PYTHON_INC_DIR variable) to have just:

        $prefix/include/python$PYTHON_VERSION
        /usr/include/python$PYTHON_VERSION
		
instead of a long list of all possible Python versioned include dirs.

This change requires that the call to AM_PATH_PYTHON be made before 
AC_INCLUDE(sysloc.in), in configure.in.  

Also, an additional sanity check for non-emptiness of the PYTHON_VERSION
variable is added to sysloc.in, right at the beginning of the Python
configuration section.
