	* added #include <config.h> to all top-level source files

	* plain.c (gsl_monte_plain_integrate): replaced myMAX by GSL_MAX

	* utils.c: move macros around to avoid double definition

Fri Aug 14 10:12:06 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* Makefile.am: I needed to add utils.h to libgslmonte_a_SOURCES to

 	get it to work with my automake

Thu Jul 30 17:31:29 1998  booth  <booth@planck.pha.jhu.edu>

	vegas1, vegas2 and vegas3 all go away.  Get them by setting the "stage"

	variabe appropriately.  Also, make _free check its argument.

	* vegas.c: minor changes, commiting by accident.

	* vegas.c, vegas-print.c, Attic/gsl_vegas_print.h, Attic/gsl_vegas.h:

	trivial stuff: eliminate compiler warnings, eliminate some unneeded variables,

	change some types to make consistent with plain and miser.

	* gsl_monte_plain.h, plain.c, plain_test.c:

	real content is the rng structure.
