malloc: bison-2.1+, prototype mismatch vs. stdlib.h (C++ mode)

[David Fang]

Hi,
	I've just encountered a problem where the compiler rejects bison's 
prototype for "void* malloc(YYSIZE_T);" because it doesn't match with 
<stdlib.h>, which looks like "void* malloc(size_t) __THROW ... ;" 
(ubuntu7).  The problem only manifests when compiling the resulting source 
file as in C++ (otherwise, the __THROW macro is empty).  It looks like the 
bison skeleton is using "defined __cplusplus" to conditionally insert this 
prototype, rather than including <cstdlib>, a standard C++ wrapper header, 
which should resolve the inconsistency, and be safely portable.
	This issue is the same on at least 2.1 and 2.3.  Does anyone else 
see this issue on ubuntu7 or other UNIX system?  (Another ubuntu7 distro 
didn't have this issue, so I need to get more feedback from my bug 
reporter.)
