2009-09-06 Richard Frith-Macdonald <rfm@gnu.org>
* Source/NSRunLoop.m: Fix for rare problem if someone changes the
system time backwards.
* configure.ac: Check for pthread.h and type sizes. Insist on having
pthread.h in order to build, now that it is a requirement.
* configure: Regenerate
* Headers/Additions/GNUstepBase/GSConfig.h.in: Declare abstract types.
* Source/NSLock.m: including pthread.h
* Headers/Foundation/NSLock.h: Avoid including pthread.h
Basically, insist on finding pthread.h at configure time, and get size
of essential types so we can avoid exposing them directly in our
public headers. This should discourage developers from using things
they shouldn't, but it does not solve the issue that copies of the base
library built with different pthread implementations on the same
platform may have binary incompatible NSLock classes (with respect to
subclassing as the pthread specific ivars differ in size). However
this is *really* unlikely to be an issue in practice.
2009-09-05 David Chisnall <csdavec@swan.ac.uk>
* Source/NSEnumberation.m: Added enumeration mutation callback.
* Source/NSEnumeration.m: Added enumeration mutation callback.
