I installed the other MinGW option and it provides libgcc_s_sjlj-1.dllwhich is not helping me actually run ldc2 on Windows :-(
It is mentioned both the in README coming with the Windows packages and the on wiki [1] that you need a Dwarf 2 EH package (-dw2) of MinGW-w64 for LDC to work.
How can we make this more clear? Cheers, David [1] http://wiki.dlang.org/Building_LDC_on_MinGW_x86
