We use ninja's response files:

# Rule for linking CXX static library.
rule CXX_STATIC_LIBRARY_LINKER
   command = E:\sandbox\MinGW32\bin\ar.exe cr $out $LINK_FLAGS @$out.rsp
   description = Linking CXX static library $out
   rspfile = $out.rsp
   rspfile_content = $in

But the problem is, that ar under windows doesn't like paths with one single '\'
and on some UNIXs doesn't support response files at all.
