bug#1177: 23.0.60; cc-mode cannot recognize pointer array declaretions

[Feng Li]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

cc-mode cannot fontify the following code correctly, where
'prUTF16Char*' should have the type face and sampleRateStrings should
have the variable face, but they both are displayed in regular text
color.

prUTF16Char*            sampleRateStrings[] = {L"48000Hz"};

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/emacs/etc/DEBUG for instructions.

I don't know much about cc-mode, but it works if you add an appropriate
entry to `c-font-lock-extra-types'. Maybe this is how it is supposed to
work?

bug#1177: 24.1.1; cc-mode cannot recognize function prototypes returning a pointer

[Stéphane Castelli]

I can confirm this bug, but with function prototypes, like this :

SDL_Surface* displayInit(void);


int* stuff(someStuff); works fine.

If i write "SDL_Surface* displayInit(void);", then erase the ';' and 
replace it by '{', then erase the '{' and re-replace it by ';', the 
coloration will work fine whatever i do next...

I see the bug happen with original scenario and this one also in 25.3,
but not in 26.1.
