How do they build their frontend? Do they use LLVM as an external
library? In that case, LLVM_ENABLE_PEDANTIC should not affect them at
all. If their frontend is integrated on the LLVM cmake build system,
they can switch off -pedantic (on svn LLVM) putting this at the top of
their CMakeLists.txt:
llvm_replace_compiler_option(CMAKE_CXX_FLAGS, "-pedantic"
"")
llvm_replace_compiler_option(CMAKE_C_FLAGS, "-pedantic" "")
