#	The provided "configure" is used to turn a config file (samples in
#	the "config" directory into commands to edit config.in into
#	a suitable config.h and to edit Makefile.in into Makefile.
#	To port GAWK, create an appropriate config file using the ones in
#	the config directory as examples and using the comments in config.in
#	as a guide.
