Enclosed is version 2.0 of UnZip by Samuel H. Smith. This software
can unarchive any .ZIP file including those created by the recently
released pkzip version 1.01. Personally, I prefer zoo for many
reasons, but there will be zip archives out there and this can help.
Unfortunately, the software as released is dependent on the TurboC
runtime library, the 80x86 byte ordering, and compiler optimization
assumptions. Not very good at all for easy porting to Unix, or for that
matter, any other C compiler/machine combination. I have made some
significant improvements to create UnZip 2.0.1 in order to increase
portability, to run under Unix, and to compile on PC's under MicroSoft
C. This software has NOT been extensively tested, but appears to
work well so far.
This version will be sent to the author just as soon as I can finally
get throught to his BBS. I had sent him the same improvements for his
last version (1.5) and explained the benefits of not having zillions of
machine specific versions, but to no avail (there are Amiga and other
hacks out there - mine should be generally more portable). Sam's
licence permits this modified distribtion when the source is included,
as it is here.
My changes among other things, perform such tasks as AUTOMATICALLY
adjusting operation for any byte-ordering (if HIGH_LOW is defined)
and handling C compilers which do not pack structures on 2 byte
boundaries (i.e. move 'longint's to the next 4 byte boundary - this
is a common, and frequently unstoppable, optimization).
