Yes, I figured that out last evening, but I had to make one correction to
the acx_pthreads macro.  On Linux it never found the appropriate library
since it looked for libpthreads instead of libpthread.

2. A header file which seems to be in different places on some platforms
   (net/ethernet.h, sys/ethernet.h, and perhaps others).  What am I

AC_CHECK_HEADERS([some.h other.h])
Will generate #define HAVE_SOME_H and #define HAVE_OTHER_H if the headers
were found. Then in your code, you can do fancy stuff with the pre-processor
based on these #defines.
Also, there is quite a couple of predefined checks for special
headers/functions that you might to check out, e.g. AC_FUNC_SELECT_ARGTYPES

Perfect!  Thanks to both you and Stepan for your help!!!
