I don't understand why should something like that be done by a
separate script, since the top-level configure already includes
multiple tests for mingw* configurations.

Another issue: This fragment of src/system.h:

  #include <dirent.h>
  #ifndef _D_EXACT_NAMLEN
  # define _D_EXACT_NAMLEN(dp) strlen ((dp)->d_name)
  #endif

is sub-optimal for systems that have the d_namlen member in struct
dirent, but don't define _D_EXACT_NAMLEN.  And since the configure
script doesn't have a test for d_namlen, there's no HAVE_* macro to
modify the above snippet to take such systems into consideration.  Is
the d_namlen member ignored on purpose?
