2000-04-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * configure.in, acconfig.h: Add configure test for garbage collector friendliness for GLib. If enabled, ENABLE_GC_FRIENDLY will be defined. * garray.c, ghash.c, glist.c, gmain.c, gmem.c, gnode.c, gqueue.c, gslist.c, gtree.c: If ENABLE_GC_FRIENDLY is defined, NULLify all memory released by the user, but cached by GLib. This lets a garbage collector have a more correct view of the actually used memory.
