some of these might be compiler version specific. i will send a patch today for 
those.

subsurface only builds with versions newer to mingw-gcc-4.6 on my side. i've 
tried version prior to 4.6 previously but got a linker error (i don't exactly 
recall the cause), but it is mingw bug.

RegQueryValueEx and RegSetValueEx take a LPCTSTR parameter, but when i enable 
UNICODE (-DUNICODE) the TEXT macro expands to something wrong e.g. "error: 
'Lname' undeclared" - where the L prefix is for wide char string, but it only 
works on string literals e.g. TEXT("sometext") =  L"sometext"

thats why in the patch i've only used casting. e.g.:
RegQueryValueEx(hkey, (LPCTSTR)name,....

ok, i will give it a try and propose changes to the makefile.
i'm sure it will work.

yep, there is no LDD from msys/mingw/gnuwin.
there are only some closed source tools like "dependency walker".

but apparently one can do:

objdump -pt libgtk-win32-2.0-0.dll | grep DLL

DLL Name: libgdk-win32-2.0-0.dll
DLL Name: libatk-1.0-0.dll
DLL Name: libcairo-2.dll
<snip>

i will try to match the versions in the eventual "src" package to the crossbuild 
DLL versions.
that are in the windows installer.
