typedef struct timespec scm_t_timespec;

it seems normal. then i add
#include <time.h>
in libguile/threads.c, but it still wrong.

the error is very strange, several months ago ,i found this error . and not only mingw but also cygwin will get this error .
i build guile-2.0.5 in slackware-current ,and it successed.
i checked the source files like threads.h, scmconfig.h __scm.h _scm.h and pthread.h in mingw/include . i can't see why scmconfig.h will influence the threads.c.
i do find the _scm.h has the relevance with threads.h. here is in _scm.h:
/* Undefine HAVE_STRUCT_TIMESPEC, because the libguile C code doesn't
   need it anymore, and because on MinGW:

   - the definition of struct timespec is provided (if at all) by
     pthread.h

   - pthread.h will _not_ define struct timespec if
     HAVE_STRUCT_TIMESPEC is 1, because then it thinks that it doesn't
     need to.

   The libguile C code doesn't need HAVE_STRUCT_TIMESPEC anymore,
   because the value of HAVE_STRUCT_TIMESPEC has already been
   incorporated in how scm_t_timespec is defined (in scmconfig.h), and
   the rest of the libguile C code now just uses scm_t_timespec.
 */
#ifdef HAVE_STRUCT_TIMESPEC
#undef HAVE_STRUCT_TIMESPEC
#endif

then i checked pthread.h in mingw/include ,it says:
#ifdef _UWIN
#   define HAVE_STRUCT_TIMESPEC 1
#   define HAVE_SIGNAL_H        1
#   undef HAVE_PTW32_CONFIG_H
#   pragma comment(lib, "pthread")
#endif

...............................

#ifndef HAVE_STRUCT_TIMESPEC
#define HAVE_STRUCT_TIMESPEC
#ifndef _TIMESPEC_DEFINED
#define _TIMESPEC_DEFINED
struct timespec {
        time_t tv_sec;
        long tv_nsec;
};
#endif /* _TIMESPEC_DEFINED */
#endif /* HAVE_STRUCT_TIMESPEC */

i can't understand :why all the declarations are ok ,but the gcc still don't know 
the struct scm_t_timespec
