[PATCH] gcc 3.3.6 patches

[Leo Davis <ldavis at fonix dot com>]

Hello,

I was able to build gcc 3.3.6 using crosstool-0.38.  I ran into a couple of 
problems, which I fixed with these patches.

One problem is the PATH_MAX problem, easily fixed by Dan Kegel's patch for it.  

The other is a build problem I noticed when gcc's configure is invoked with 
--without-headers.  It builds a temporary script in 
$TMPDIR/cNf<PID>/cNf<PID>.tgt.  It later invokes this script.  I don't know 
if this patch is absolutely necessary to build.

Leo
