c2nim - Multi-character constants and structs

[emg]

Hi all,

I'm trying to use c2nim tool to convert some internal c library's header and I 
ran into two issues. The C Header has preprocessor defines like the following
    
    
    #define TK_DataType_FBR                     'FBR8'
    

Trying to parse this gives me an error like this 
    
    
    " Error: missing final ' for character literal".
    

The issue is if it's just a few constants, I would convert them manually by 
myself but the header has hundreds of such macros.

Another issue I ran into is with structs that have members conditionally 
declared by macros like this
    
    
    typedef struct {
                    #ifdef      LOW_PRECISION
                            short       _xS16;
                            short       _yS16;
                    #else
                            int _xL32;
                            int _yL32;
                    #endif
            } GIS_Pt;
    

This gives me an error like this
    
    
     Error: identifier expected, but found '}'
    

Any help would be much appreciated. Thanks.
