Hi,

There seems to be a bug in exicyclog. If log_file_path is set in the
configuration file to be ":syslog", then the script "guesses" where the
logs files are, rather than using the compiled in default. In our case
the guess is not the same as the compiled default, so the script
suddenly stopped working when I started to use syslog...

The following patch checks to see if log_file_path is "". If so, it
attempts to read it from exim with no configuration file to get the
compiled in version, before it falls back to the previous guessing code.

This is against exicyclog from exim 4.44. It seems to be the same with
exim 4.50, too.

Matthew
