PING: [PATCH] Fixing parse errors in c-exp.y

[Abhijit Halder <abhijit dot k dot halder at gmail dot com>]

Hi all,

This patch is about fixing parse error coming when gdb tries to parse
a pointer to a function pointer. e.g. (int)(**)(int) and the
associated problem, defined in PR 9837, which says wrong parsing when
pointers appear in function argument e.g.  (int)(*)(int*)

Please review this.

Thanks,
Abhijit Halder
