[kaffe] Problems compiling kaffe (gcc 3.2 & 3.1.1)

I have a patch/workaround for that in our package. What happens is when 
compiling with explicit -I/usr/include or -I/usr/local/include, gcc 
warns you that this is bad practice. It turns out that the (generated) 
configure script doesn't know about the warning as the AC_CHECK_HEADER 
(IIRC, that was this one) checks that no output is emitted. That is, it 
considers the feature as missing. Thus, HAVE_SOME_HEADER_H is not 
defined and the necessary includes are not... included.

As other packages do, the clean way to fix that is to check the tested 
include path prior to adding it to CPPFLAGS. For sure, -I/usr/include is 
bad if gcc was configured with prefix=/usr. -I/usr/local/include was 
questionable and you may want to consult the gcc@ mailing-list archives.

Bye,
Gwenole.
