[webkit-dev] Urgent help!

Hi,

Currently I'm trying to compile Webkit+Gtk with DFB as a backend using
gcc-3.2.3 with some modification on the source code. However, I encounter
error as following:

The changes I made in Webkit are as following:
I) in Node.h, I change the bit field 
    unsigned m_styleChange : 2;
    bool m_hasId : 1;
   .......
    const bool m_isContainer : 1;

to :

struct _NodeBits {
        unsigned m_styleChange : 2;
        bool m_hasId : 1;
        .........
        bool m_isContainer : 1;
    } nodeBits;

I did the same for all bit fields.

II) I modify GNUMakefile.am to change webkitmarshal.cpp to become
webkitmarshal.c due to error compiling because of G_GNUC_UNUSED

III) In JavascriptCore/VM/CodeGenerator.cpp, I change ALWAYS_INLINE to
inline

IV) In Webkit/gtk/webkit/webkitdefines.h, I replace 
#define WEBKIT_API __attribute__((visibility("default"))) 
with 
#define WEBKIT_API 
because I get a lot of warning message like "warning: `visibility' attribute
directive ignored".
same also with 
//#define JS_EXPORT __attribute__((visibility("default")))
#define JS_EXPORT
in JavascriptCore/API/JSBase.h.

May I know if above modification will cause the error or is there any
further modification I should do?

Thanks in advance.

Regards,
Belinda
