In a patched version of xv.h I have:

        /* lots of things don't have <malloc.h> */
        /* A/UX systems include it from stdlib, from Xos.h */
        #ifndef VMS   /* VMS hates multi-line '#if's */
        # if !defined(ibm032)                    && \
             !defined(__convex__)                && \
             !(defined(vax) && !defined(ultrix)) && \
             !defined(mips)                      && \
             !defined(apollo)                    && \
             !defined(pyr)                       && \
             !defined(__UMAXV__)                 && \
             !defined(bsd43)                     && \
             !defined(aux)                       && \
             !defined(__bsdi__)                  && \
             !defined(sequent)                   && \
             !defined(__FreeBSD__)               && \
        #  if defined(hp300) || defined(hp800) || defined(NeXT)
# include <sys/malloc.h> /* it's in 'sys' on HPs and NeXT */
        #  else
        #   include <malloc.h>
        #  endif
        # endif
        #endif /* !VMS */

In this example only the first seven 'defined' (up to and including defined(pyr)) are emphasised with font-lock-preprocessor-face, then again those in the '# if defined(hp300)' line. Alan Mackenzie explained that this is due to "problem with jit-lock-mode, which doesn't cope very well with language constructs which extend over several lines. You can see this by disabling jit-lock-mode with (setq font-lock-support-mode nil), after which the entire file fontifies properly." The last observation I can make, too. My set-up is:

        (cond ((fboundp 'global-font-lock-mode)
           ;; Turn on font-lock in all modes that support it
           (global-font-lock-mode 1)
        ;   (setq font-lock-multiline 'undecided')
           (setq jit-lock-stealth-verbose t)
           (setq jit-lock-mode t)
        ;   (setq jit-lock-stealth-load 80)
           ;; Maximum colors
           (setq font-lock-maximum-decoration t)))


        '(font-lock-beginning-of-syntax-function nil t)
        '(font-lock-global-modes (quote (not)))
        '(font-lock-keywords-case-fold-search nil t)
        '(font-lock-keywords-only nil t)
        '(font-lock-mark-block-function nil t)
        '(font-lock-maximum-decoration t)
        '(global-font-lock-mode t nil (font-core))



Windows, c'est un peu comme le beaujolais nouveau: à chaque nouvelle cuvée on sait que ce sera dégueulasse, mais on en prend quand même, par masochisme.
