Please keep Windows-specific code out of ser-base.c. Is read() on
MinGW fully blocking? Or will it return whatever is available and
only block if nothing is available. Then you could use gdb_select()
to check whether input is available on the pipe.
Otherwise, you should think about introducing an asbtraction layer for
reading from error_fd.
