I am reasonable sure that last time, long time ago,
there was not this problem on building guile 2.0.11.

I suspect is due to the re shuffle of cygwin header
plus the local version of "signal.h".
But I am a bit lost in following all the chain:

------------------------------------------------------

        clock_t si_utime;   /* user time */
----------------------------------------------------------

local signal.h has a structure like:

-------------------------------------------------
/* Define pid_t, uid_t.
    Also, mingw defines sigset_t not in <signal.h>, but in <sys/types.h>.
    On Solaris 10, <signal.h> includes <sys/types.h>, which eventually 
includes
    us; so include <sys/types.h> now, before the second inclusion guard.  */
#include <sys/types.h>

/* The include_next requires a split double-inclusion guard.  */
#include_next <signal.h>
---------------------------------------------------

PS: I rebuilt 1.8.8 and it has no problem.
    But it clearly has a different structure.

Marco
