Hi Gnu Gurus,


There appears to have been a suble change in gcc's include file behavior.  The
compile options:

	-Idira -Idirb

    with file structure:

	dira:
	   foo.h
	dirb:
	   foo.h fooinclude.h

Yields different results under 2.x that differ from 1.37x.  In particular, if
fooinclude.h contains `#include "foo.h"', and your source includes
"fooinclude.h", then under 1.37x, you would get dira/foo.h (in the order of the
options), under 2.x you get dirb/foo.h (the "current" directory has
precedence).

Was this intended?  Adding the options "-I- -I." doesn't really fix the
"problem"; that fails when you compile source from a subdirectory.

Thanks for your time,

        -- Stan
