I've been spending some days over this issue. I think that as the WideCharToMultiByte
function is something Microsoft-related, the core problem is in using a gcc compliant compiler (as MinGW: I'm using it too).

I'd really like to contribute someway to this __wonderful__ project, but I think I don't have the necessary skills aboud C/C++ development. Anyway, I can point out this: the cygwin support __doesn't__ automatically introduce the MinGW support, as cygwin is a POSIX-environment over a Windows one, while MinGW is a gcc porting for Windows (so calling make -f Makefile with MinGW doesn't produce anything good ;-P ). And it's a pity, as I spent 20mins to build POCO on my Debian and something like 4 days to do the same on Windows-without-VisualStudio (and, actually, I couldn't get it properly built, so I had to use VS).
Any suggestion would be appreciated, and I'll try to give you a feedback on my activity to make POCO MinGW-compliant.
(p.s. sorry for my English!)
