Subject: * keyboard.h (num_input_events): Now uintmax_t.
X-Git-Tag: emacs-pretest-24.0.90~104^2~152^2~171
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=3300e6fd43c4059de955cddc37ec4212dab2b085;p=emacs.git

* keyboard.h (num_input_events): Now uintmax_t.

This is (very slightly) less likely to mess up due to wraparound.
All uses changed.

 	* buffer.c: Integer signedness fixes.
 	(alloc_buffer_text, enlarge_buffer_text):
 	Use ptrdiff_t rather than size_t when either will do, as we prefer
