1999-07-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * configure.in, acconfig.h, gutils.c: Added a g_memmove replacement for platforms without memmove, where bcopy can't handle overlapping copies and the corresponding checks, which is taken form the PERL Configure routine. * glib.h: Updated the commentary about g_memmove to be right and more GLib-like. * configure.in: Removed test for rand_r, as it isn't used anymore.
