# Configure.in
#
#  This file tests for various compiler features needed to configure 
#  the gtkmm package.  Original skeleton was provided by Stephan Kulow.
#  All tests were written by Tero Pulkkinen, Mirko Streckenbach, and 
#  Karl Nelson.
#
#  NOTE! IF YOU DO CHANGES HERE, CHECK IF YOU NEED TO MODIFY .m4 TOO!!!
