>Description:
When I try to compile any c program that includes the "fuse.h" header, it does not compile.

Here is the GCC output:

>How-To-Repeat:
Compile this file, which I've called main.c, with the command "gcc main.c":

#include <fuse.h>

int main() {
}
>Fix:
Looks like this might be a simple case of some missing typedefs... presumably the header file just needs something like "typedef __register_t register_t".

Including sys/types.h in main.c does not fix the problem.
