bug-report: autoscan generating wrong macro call

[John Calcote]

Hi -

autoscan (v 2.61) seems to be generating a call to AC_CONFIG_HEADER 
(singular). I believe this macro is out of date (although apparently 
still supported). The correct call should be to AC_CONFIG_HEADERS (plural).

This is not really a big deal except that AC_CONFIG_HEADER is no longer 
documented in the autoconf manual.

Thanks,
John
