#3 UnZip-Decompress & enhanced deflate (meth #9), winzip only

[Gautier de Montmollin]

unzip-ada (v.30) rejects many "enhanced deflate" files made by winzip 10.0 (...
sometimes CRC errors, or:
unzip-decompress.adb:1711 Huffman tree errors: huft_incomplete
unzip-decompress.adb:1542 Inflate_Stored block length check fails
unzip-decompress.adb:1469 Inflate_codes E = invalid
unzip-decompress.adb:1809 Inflate_Block block type 3
)...
but accept all archives with the same contents and compression
method from 7-zip (7z -mm=deflate64)!
