syslogd: strip trailing NULs
 2007-11-06 01:38:46 +00:00
Paul Fox
cb981638f5 change safety check on zip header to allow for extra length, and 
revert the header read to use the correct constant rather than
sizeof.  at least one version of gcc (armv4-linux-gcc-3.4.1) pads
the struct to 28 bytes in spite of the packing.
