>Severity:      non-critical
>Priority:      medium
>Category:      portability
>Class:         sw-bug
>Release:       cvs-1.11.5
>Environment:
        
NetBSD-1.6L/i386
>Description:
The configure script checks for the fnmatch function (used
by cvs via configure.in's AC_FUNC_FNMATCH) in autoconf 2.53
do not detect fnmatch on NetBSD correctly. Thus, the compatibility
function in the cvs sources is unnecessarily used.

This was fixed somewhere between autoconf 2.53 and 2.57.
>How-To-Repeat:
Run the configure script on NetBSD-1.6 (and probably other versions too).
>Fix:
Regenerated configure with a newer autoconf.
I tested with 2.57, and that worked.
