configure error in 990805 STABLE snapshot

[Brian Edmonds]

After deciding to upgrade my home news server (Linux 2.0.36, libc5) from
2.1 I downloaded inn-STABLE_2_2-1999-08-05_03-03 and attempted to build
it.  I got the following error from configure:

checking for close on exec style... configure: error: Must set CLX_STYLE

Glancing over the script I'd guess this means it didn't find a CLX_STYLE
that it liked.  Any other details that would be useful, please let me
know.

Brian.
