>Description:
ufsmount.h is broken for C++. It uses a reserved keyword "export"
for a member of the struct ufs_args:
struct ufs_args {
char *fspec; /* block special device to mount */
struct export_args export; /* network export information */
};
alex@zerogravity ~ $ cat ufsmount.cc
extern "C" {
#include <sys/param.h>
#include <sys/mount.h>
#include <ufs/ufs/ufsmount.h>
}
alex@zerogravity ~ $ c++ --version

/usr/include/ufs/ufs/ufsmount.h:45: syntax error before `export'
>How-To-Repeat:
see above
>Fix:
As a workaround, you can #define export _export before you include
ufsmount.h, and undefine it later. This is an ugly hack, but working
for certain uses.
A real fix is to proberly name the member of the struct.
