# FIXME: Disable the runtime tests for MSVC until we have a MS compatible header.
#
# The runtime tests include src/runtime/runtime_internal.h which was written 
# to only support clang (GCC's front end is close enough it works fine as well). 
# We originally setup the tests to compile with clang (in the same way as the actual 
# runtime bitcode files), but that wasn't very clean and didn't integrate well with 
# the other tests, so we switched to just using the native system compiler. 
# Sadly MSVC isn't compatible with the current runtime_internal.h which would need
# some platform specific ifdefs for attributes and types that are causing compile 
# errors.
