[PATCH] font problem in 23.0.60

[Chip Coldwell]

A recent CVS snapshot (May 27) exhibits the following bug:

$ xfd -fn -adobe-courier-medium-r-normal--*-120-75-75-m-70-iso10646-1

works as expected, shows the font exists on my system as
-adobe-courier-medium-r-normal--12-120-75-75-m-70-iso10646-1.

$ emacs -fn -adobe-courier-medium-r-normal--*-120-75-75-m-70-iso10646-1
Fatal error (11)Segmentation fault (core dumped)

I did a little debugging, and found that the SIGSEGV is caused by
taking the CDR of an integer.  This patch fixes the SIGSEGV

   else
     dpi = f->resy;
   pixel_size = POINT_TO_PIXEL (point_size, dpi);

However, now I get

src/emacs-23.0.60.3 -fn

Font `-adobe-courier-medium-r-normal--*-120-75-75-m-70-iso10646-1' is not

even though it is defined.  I will continue to debug that problem as
time permits.
