[PATCH] Step over Objective-C dispatch function

- Subject: [PATCH] Step over Objective-C dispatch function
All Objective-C messages are called through the standard dispatch
function. This patch steps right into the method without the user having
to go through the dispatch function manually.
2003-01-02 Adam Fedor <fedor@gnu.org>
* infrun.c (handle_inferior_event): Add test to step over
Objective-C dispatch function.
* Makefile.in (infrun.o): Add $(objc_lang_h)
