any idea why the following code fails?
#include <setjmp.h>
#include <stdlib.h>
struct JumpBuffer {
jmp_buf buf;
};
inline int
mysetjmp( JumpBuffer *j )
{
return ::setjmp( j->buf );
}
…
g++ complains at the “return” line with a message:
parse error before `(’
(this code is from xf86 4.1)

It’s getting expanded to
return :: (__sigjmp_prolog(( j->buf ), ( 1 )), _setjmp( j->buf )) ;
This looks to be a bug in our header file.
Thanks Colin,
do you have a quick fix that I can just modify the header file, to
get my port going.

Thanks Colin, it works! You are good man.
