(FYI, you may want to check it with new_mini_epn [ distributed with
Nagios ] to see if ePN is going to complain about it).

Yep, base/checks.c. IIRC. checks.c also sets the value for $delete that
is passed to eval_file (see
http://nagios.cvs.sourceforge.net/nagios/nagios/base/checks.c?view=marku
p
use the source).

The value that becomes $delete is set in checks.c as the value of
DO_CLEAN.

I think this value is set by configure.

You may want to remove the config.cache (or whatever it is) and
reconfigure with the appropriate settings.

(On an unrelated matter, thank you for this thread since I think a
simple mod to p1.pl will deal with the recompilation problem of putting
symbols in the same stash and thereby raising the subroutine already
exists exception).

Yours sincerely.
