Are you building on a mingw32 machine or on a Linux machine (ie. doing a Canadian
cross compile) ?
The Canadian cross is more likely to succeed.

libc++ is now part of GCC.  It should compile fine and all features should be
available as far as I know.  To get I/O to work is the same as for the C
library.  You need to write some stubs for write(), read(), etc.

The linker options "-nostartfiles", "-nodefaultlibs" and "-nostdlib" are
available so that various files are not used automatically.  You can also modify
the specs file if you want to.
