Version: 1.0.6-win
Neither the x64 nor the x86 version managed to compress a 4.5 GB file.

bzip2: Input file large.file is not a normal file.

Small testfiles (few KB) worked.

bzip2 uses the _stat function on Windows to determine whether the file to compress exists. This will return an error if the file size is greater than 232 - 1 bytes, resulting in the 'not a normal file' output.

I've added a patch to switch to _stati64 instead. This variant of the stat function supports 64-bit file sizes.

I've built a new release (v1.0.6.1) that includes the patch.

Thank you for this quick fix! I cannot believe that I am the first person to complain about this...

Fix a 'not a normal file' error when compressing large files on Windows.

The bzip2 command on Windows would report a 'not a normal file' error
for files of size greater than 2^32 - 1 bytes.

Use _stati64 instead of _stat so that a successful result is returned
for large files.

The bzip2 command line would report 'not a normal file' for files of
size larger than 2^32 - 1 bytes.

Patch bzip2.c to use _stati64 instead of _stat so that a successful
result is returned for large files.

Resolves philr/bzip2-windows#3.
