[Bug other/37036] New: fixincludes does not understand sysroot!

["jayk123 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

gcc 4.3.1

given build=platform1 (i686-pc-cygwin)
given platform2 (sparc-sun-solaris2.10) 

mkdir /obj
mkdir /obj/1
cd /obj/1
# ensure up to date native tools
/src/gcc/configure -build platform1 -host platform1 -target platform1
-disable-bootstrap -disable-multilib -enable-languages=c,c++ && make && make
install


# cross tools -- have setup sysroot ahead of time
mkdir /obj/2
cd /obj/2
/src/gcc/configure -build platform1 -host platform1 -target platform2
-disable-bootstrap -disable-multilib -enable-languages=c,c++ && make && make
install

# now the problem part
mkdir /obj/3
cd /obj/3
/src/gcc/configure -build platform1 -host platform2 -target platform2
-disable-bootstrap -disable-multilib -enable-languages=c,c++ ???? && make &&
make install
DESTDIR=/usr/local/platform2/install

tar up the install
scp
untar on host
try it out

errors, because fixincludes uses the build /usr/include instead of the
sys-rooted /usr/include.

Even using -with-build-sysroot /usr/local/platform2/sys-root does not work.
Apparently. I have to go read the code.

Specific workaround:
delete include-fixed/math.h


I think this is particularly problematic in that the requirements here are
"unique". Nowewhere else does the two platform canadian cross need the
host/target sysroot. It's builtin to the cross compiler.

The cross ocmpiler also has the correctly fixed includes.
So another workaround is to use them.
But they might be from an older version of gcc/fixincludes.
