Hi,
I am using gcc4.3 and glibc 2.8. During compilation am getting the
compilation mentioned below.
Can any one help me out.
I am not sure if it is a bug of new gcc.

/glibc/x86-linux2/../sysroot/usr/include/wc
har.h:341: multiple definition of `wctob'

Some background of this error. I have add these 6 line to my .cpp file
to avoid some error(error: '__extern_inline' does not name a type)

#ifndef __extern_inline
#define __extern_inline
#endif
#ifndef __wur
#define __wur
#endif

Thanks

This should not be necessary.  __extern_inline should be defined by
sys/cdefs.h.  You should find out why that is not happening.

Defining __extern_inline to be empty is never correct.  There are two
possibilities, and sys/cdefs.h should select the right one.
