There is something in the configure.ac about:

  AH_TEMPLATE([GC_WIN32_PTHREADS],    [Define to support win32-pthreads.])

I apologize for the back and forth here, I wish I knew more about
mingw.

Well OK, this should still work.

This indicates that struct scm_t_timespec is not defined.  I don't know
how this could be: can you grep libguile/scmconfig.h for scm_t_timespec
?

I assume configure detected struct timespec, but that threads.c does not
include the right header.  Can you add

  #include <time.h>

to the top of threads.c to see what happens?

I have committed something locally that will cause scmconfig.h to always
include time.h.

Thanks for the report,

Andy
