5 Unzip 6.0c fixes for MinGW - ID: 1816742

Last Update: Settings changed ( willus )

Details:

I made two mods that got unzip 6.0c to work under MinGW.

1. I put this line in w32cfg.h right at the beginning, just after #define
__w32cfg_h

#define USE_STRM_INPUT

2. I changed the line in unzpriv.h from:

#define Z_OFF_T long

... to ...

#define Z_OFF_T long long

That did the trick, and now unzip 6.0c seems to correctly process all of my
zip 3.0f archives.

Date: 2007-10-20 04:15 Sender: willus Follow-up: These same fixes seem to be required by the latest version of unzip 6.0d (r5) to get it to work under MinGW. Also, the changes I made above may break the code for other platforms since I made no effort to isolate them to MinGW. For the final release, they should be made so that they are conditional to a MinGW compile (and whatever other Win32 compiler they may fix). Note that I forced USE_STRM_INPUT because the 64-bit zlseek() in MinGW doesn't seem to be working consistently. I'm using a version of MinGW that's a few years old (MinGW 3.1.0, gcc 3.4.0), so this might be fixed in a more recent version of MinGW.
