Thu Jan 5 13:37:42 1995 Cameron Heide (heide@ee.ualberta.ca) * [memory/global.c] GlobalCompact should now return the correct value when the largest run of free blocks includes the last block. * [windows/mdi.c] Tiling and cascading windows without any MDI children should no longer crash (assuming no-op is the correct thing to do). Sun Jan 1 23:30:25 1995 Fons Botman <botman@rabo.nl> * [objects/font.c] GetTextExtentPoint: fixed debug output, str is counted string, not zero terminated. * [if1632/relay.c] DLLRelay: when debugging_stack got segv, added upper bound for stack dump.
