aria2 is a download utility with resuming and segmented downloading.

Using the makefile aria2.mak.

I successfully ported aria2 to Windows using the Debian MinGW cross-compiler. While aria2 compiles under native MinGW and Cygwin, the resultant executable is buggy, and numerous unit tests fail.

Update: I installed gcc 4.3.0 in MinGW using get_mingw.cmd and am now able to produce working binaries in my Windows environment. This leads me to believe that gcc 3.4.5 is not reliable under MinGW.

Please note that while the developer states in the README file: "aria2 is in very early development stage", I've successfully downloaded using the following methods:

• HTTPS
• HTTP
• FTP
• Local metalinks
• Remote metalinks
• Local torrents
• Remote torrents

I'm aware of the following issues:

• Azureus is much faster than aria2 on my system. Initially, I thought this was due to my firewall blocking incoming UDP traffic. As aria2 only uses TCP and not UDP sockets, this does not appear to be the reason why Azureus is faster. More research is needed.
  
  
• I wasn't able to directly download the metalink http://curl.haxx.se/metalink.cgi?curl=tar.gz. A workaround would be:
  

  aria2c.exe -o local.metalink --follow-metalink=false http://curl.haxx.se/metalink.cgi?curl=tar.gz
  aria2c.exe -M local.metalink
  

The following issues have been fixed:

• Rename bug due to MinGW's rename() not deleting the destination file, if it already exists.
• HTTPS downloads failed prior to version 0.11.1+1.
• Downloads failed at 2GB prior to version 0.11.1+1.
• Due to MinGW's sscanf() function lacking support for the %Ld specifier, files larger than 2147483648 bytes will not download correctly via FTP. This is not an issue for the Cygwin version.
