lseek always include windows.h?

I got this error building GNU SASL for uClinux:

Configure said:

checking whether lseek detects pipes... no

Any ideas?

Is this logic wrong perhaps:

       AC_LINK_IFELSE([
#if (defined _WIN32 || defined __WIN32__) && ! defined __CYGWIN__
/* mingw mistakenly returns 0 when trying to seek on pipes.  */
  Choke me.
#endif],
         [gl_cv_func_lseek_pipe=yes], [gl_cv_func_lseek_pipe=no])
     fi])

Generally, it seems lseek gets pulled in by getpass, via fseeko.  I
wonder if getpass need to use fseeko?
