Ok got as far as generating NINJA build files, but now the build 
is failing...


C:\LDCDEV\build-ldc-x64>ninja
[1/104] Linking CXX executable bin\FileCheck.exe
FAILED: bin/FileCheck.exe

error LNK2019: unresolved external symbol __std_find_trivial_8
error LNK2001: unresolved external symbol __std_find_trivial_1
error LNK2001: unresolved external symbol 
__std_init_once_link_alternate_names_and_abort

and others

Actual output is prob 1000 lines but seems to be mostly 
unresolved eternal symbols, in llvm.

Any ideas?
