Clang extension for BOOL and nil

[Vincent R.]

Hi,

Do you think it would be possible to use clang extension to define type 
like BOOL and nil ?
Actually I am using clang to rewrite objc into another syntax and 
macros are not really helpful for this,
I would need to get a specific type for BOOL/YES/NO and not just 
(unsigned char)/(BOOL)1/(BOOL)0.
When compiling a Cocoa application on mac with clang there are the 
following definitions :

#if __has_feature(objc_bool)
#define YES             __objc_yes
#define NO              __objc_no
#else
#define YES             ((BOOL)1)
#define NO              ((BOOL)0)
#endif


#ifndef nil
# if __has_feature(cxx_nullptr)
#   define nil nullptr
# else
#   define nil __DARWIN_NULL
# endif
#endif

I suppose it could help me in my task but I am wondering if it would 
work with GNUStep,
and of course I will try tonight once I am at home on my linux box but 
if someone(let's say David C. :-) )
have some idea about that.
