Hi Andrew,

Thanks for the comments.

Actually, when we say "--disable-hosted-libstdcxx", we mean that we only want a
limited set of headers (same as the one in "freestanding" mode).
But as per the info below, "freestanding" mode supports typeinfo and exception
headers.


In "freestanding" mode only the following headers can be safely used:
•cstdarg
•cstddef
•cstdlib
•exception
•limits
•new
•exception
•typeinfo
