Some clients seem to use a blank + one if a session setup has succeeded. + - ISC patches from imb@asstdc.scgt.oz.au + - the client now tries to do name registration using a unicast. + Let me know if this helps anyone. + - tried to add a "contributed" line to each OS in the Makefile. + +1.5.39 18/2/94 + - fixed silly C code that only worked with some compilers + - fixed another silly bug in nameserv.c that caused it to seg fault + +1.5.40 21/2/94 + - removed the from (IP) message so people don't worry about 0.0.0.0, + it's redundant anyway. + - changed the client so the crypt key isn't printed + - changed the structure of switch_message() to use a list of functions. + This improves the debug info. + - made SMBopen ignore supplied attribute as per X/Open spec + - made SMBopen fail if file doesn't exist in all cases.
