Tcl Source Code

Any stubbed & threaded extension that includes 
tclUnixPort.h and uses any of the procs readdir, localtime, 
gmtime or inet_ntoa will fail with link errors on Unix with the 
current Tcl HEAD. (ex: current threaded TclX 8.4 HEAD fails 
to link)

This is due to the following defines in tclUnixPort.h:
    #define readdir(x)TclpReaddir(x)
    #define localtime(x)TclpLocaltime(x)
    #define gmtime(x)TclpGmtime(x)
    #define inet_ntoa(x)TclpInetNtoa(x)
and the fact that those four Tclp* procs are not exported in 
stubs.

either these four defines need to be restricted to be 
internal to Tcl or the four Tclp* procs need to be added to 
tclInt.decls as in the attached patch.

both threaded and non-threaded Tcl as well as associated 
threaded & non-threaded TclX 8.4 build fine with the patch.

This should go into b2 if possible as it potentially breaks 
any threaded stubbed extension.

Please reupload this patch - it got truncated.  Or better yet, it 
looked good for the parts that were there, so just apply it.

attached improved patch that - in a non-threaded build - calls 
through to e.g. gmtime from TclpGmtime instead of returning 
NULL.
