Build fail incomplete element type struct timespec

[JEdward7777]

The following errors prevent ptfs from compiling.

/usr/include/fuse/fuse.h:444:54: error: array type has incomplete element type ‘struct timespec’
  444 |  int (*utimens) (const char *, const struct timespec tv[2]);
      |                                                      ^~
/usr/include/fuse/fuse.h:444:45: warning: ‘struct timespec’ declared inside parameter list will not be visible outside of this definition or declaration
  444 |  int (*utimens) (const char *, const struct timespec tv[2]);
      |                                             ^~~~~~~~
/usr/include/fuse/fuse.h:867:29: error: array type has incomplete element type ‘struct timespec’
  867 |       const struct timespec tv[2]);

Searching the error message fatx also had the same error and the same solution worked.

The fatx issue references this pull and this stackoverflow reference.

Attached is a patch which implements the same correction which allows the compile to proceed and work.

Not sure if the patch didn't get mangled by MarkDown, so basically you need to add the following blob to the top of ptfs.c.

#define _XOPEN_SOURCE
#if __STDC_VERSION__ >= 199901L
#define _XOPEN_SOURCE 600
#else
#define _XOPEN_SOURCE 500
#endif /* __STDC_VERSION__ */
