Unix-LhA on DECstations has a bug when archiving directories recursively.
The reason is a problem in C with char vs. unsigned char. The problem is
fixed, if you replace the function call

	rindex(.., DELIM2)

with

	rindex(.., (char) DELIM2)

in src/header.c three times. I include a patchfile below.
