aria2c.exe was generated using Debian cross compiler:

 * gcc-mingw32      4.4.2-5
 * mingw32-binutils 2.20-0.1
 * mingw32-runtime  3.13-1 with included mingw_snprintf.patch

It was static build so no extra dll necessary.

Before building the source, I applied aria2-1.9.3-mingw.patch to fix
compile error and some tweaks for Windows environment.

I compiled aria2 with following libraries:

 * openssl 1.0.0
 * expat 2.0.1
 * sqlite 3.6.23.1
 * zlib 1.2.5
 * c-ares 1.7.1

This build has differences from original aria2-1.9.3 release:

 * --disable-ipv6 is enabled by default.
