| Sample code to use it in configure.in, when the program _needs_ the
| win32 API:
| 
| AC_CANONICAL_HOST
| 
| case "${host}" in
| *-*-cygwin*)
|         AC_PROG_CC_WIN32
|         if $ac_cc_win32; then
|         dnl do nothing here - any header checks /library checks etc
| later in configure.in will now pass
|         else
|             echo "configure: error: Win32 API needed and no acceptable
| cc could be found" 1>&2;
|             exit 1;
|         fi        ;;
| esac

My opinion is that AC_PROG_CC_WIN32 should contain an AC_REQUIRE of
AC_CANONICAL_HOST, and should ensure the case $host itself.
