Thu Nov 4 1999 Michael Hanni <mhanni@sprintmail.com>
* Source/NSObject.m: added FreeBSD specific code in
initialization so that the FPU is intialized with the correct
exception flag. This allows NSConnection to work on FreeBSD (gdnc,
gdomap, gpbs.)
Thu Nov 4 10:52:00 1999 Richard Frith-Macdonald <richard@brainstorm.co.uk>
* Source/NSArray.m: use NSLog() to warn about attempts to remove nil.
