## Revision 1.5  2005/10/06 20:06:00  nadya
## add definitions for configure macros that are missing from autoconf v < 2.54
## will need to run bootstrap on install hostbefore running configure.
##
## Revision 1.4  2005/10/04 23:47:01  nadya
## add check for autoconf v 2.53 or later. If 2.53, then use macros in m4/
## for creating aclocal.m4 file
##
## Revision 1.3  2005/09/15 21:36:43  nadya
## move bootstrap to top
##
## Revision 1.1  2005/09/13 22:07:24  nadya
## move gnu-related files in config/
##
##
## Purpose: to generate GNU configure script. 
## execute this file IFF:
##
## (1) there is no configure scirpt in the top most directory
##
## (2) you have edited one of 
##         configure.ac 
##         config.h.in  
##         Makefile.am
##
## (3) autoconf/automake tools on your system are of different version then
##     those used to create this distribution. In this case, the autoconf
##     and automake-related files may not work and will need to be recreated
##     This distribution was created with GNU autoconf 2.59 and automake 1.9.2
