I don't think so.

With O_TEXT we will run into another trouble as length of data in memory will 
be smaller than one in file. As result read_include_file() will complain that
input file is shorter than expected.

So unless we want to remove that check, O_BINARY must stay there.

Current patch changes mode to O_BINARY in rather specific case when
one is feeding source in gcc from pipe. For example 
	cat foo.c | gcc -c -x c -o foo.o -
In this case file is opened in text mode by default, and I'm getting a warning 
I mentioned above.
