ldc-mingw - Windows sample - undefined reference to `_Dmain'

[dnewbie]

Error 'undefined reference to `_Dmain'' when compiling 
samples\d\winsamp.d.

Workaround:
a) add main() that calls myWinMain
b) run objcopy for setting subsystem=windows and to get rid of 
the 'DOS window':
objcopy --subsystem windows:5.00 winsamp.exe winsamp2.exe
