Philipp Stephani 109eb1e7e2 Fix undefined behavior when fetching glyphs from the display vector. 
You can trigger this rather obscure bug by enabling selective display
if the second glyph in its display vector has an invalid face.  For
example, evaluate

(set-display-table-slot standard-display-table
                        'selective-display [?A (?B . invalid)])

and then enable selective display.

* src/xdisp.c (next_element_from_display_vector): Check whether next
glyph code is valid before accessing it.

This directory contains the source files for the C component of GNU Emacs.
Nothing in this directory is needed for using Emacs once it is built
and installed, if the dumped Emacs is copied elsewhere.

See the files ../README and then ../INSTALL for installation instructions.

The file 'Makefile.in' is used as a template by the script
'../configure' to produce 'Makefile'.  This is the file which actually
controls the compilation of Emacs C source files.  All of this should
work transparently; you should only need to change to the parent
directory, run './configure', and then run 'make'.
