<pre>We're running into a problem where configure fails because clang-cl doesn't
accept the LDFLAGS that are passed to it, while cl.exe does. This makes using
clang-cl with autoconf and custom LDFLAGS very difficult.
Since, we don't want to ignore unknown options to clang-cl one option would be
to add a flag something like '-fignore-options=[all the options to be
ignored]". This gives projects using autoconf a way to hack things into
working.
Alternatively, we could modify the default clang-cl behavior to match cl by
accepting unknown arguments, and add a '-fstrict-option-parsing' argument that
rejects unknown options. This allows clang-cl to be a drop-in replacement for
cl while allowing projects that don't need this the option to opt into sane
behaviour.</pre>
