gcc warns about this:

zip2john.c: In function ‘process_file’:
zip2john.c:262:33: warning: ‘best_off’ may be used uninitialized in this 
function
zip2john.c:262:43: warning: ‘best_crc’ may be used uninitialized in this 
function
zip2john.c:262:53: warning: ‘best_cmp_size’ may be used uninitialized in 
this function

Not sure if you get them or if they are of any importance, just wanted 
to let you know.

Also, it still fails self-test when built [linux-x86-64] with gcc: 
get_hash[0](19).

icc emits these cryptic warnings:
ipo: warning #11021: unresolved inflateEnd
         Referenced in /tmp/ipo_iccjZeMHE.o
ipo: warning #11021: unresolved inflate
         Referenced in /tmp/ipo_iccjZeMHE.o
ipo: warning #11021: unresolved inflateInit2_
         Referenced in /tmp/ipo_iccjZeMHE.o

Not sure if that has anything to do with why gcc fails, but the icc 
build works fine:

I used the 2011-CrackMeIfYouCan_partX.zip files as real-world test. It 
cracked them in 2 minutes, 6133K c/s :)
