CVS Gnat can't x-compile s-auxdec.adb to hppa

[Matthew Wilcox]

I'm trying to cross-compile Gnat from an i386-debian-linux box to
hppa-linux in order to bootstrap Gnat on hppa-linux.  Software involved:

native gcc version 2.95.4 (Debian version 1:2.95.4-7)
native gnat version 3.14p (20010503) (Debian version 3.14p-3)
cross-compiling gcc version 3.0.3

grabbed CVS head as of approx 11:30am MST today.  Configured it thus:

../gcc/configure --target=hppa-linux --prefix=/opt/palinux --disable-shared \
	--enable-languages=ada

(the cross toolchain is already installed in /opt/palinux, so it picks
up the appropriate binutils from there).

`make' is uneventful.  Then,

cd gcc; make gnatlib_and_tools

(...)

../../xgcc -B../../ -c -g -O2 -g -O2 -W -Wall -gnatpg -I. -I/home/willy/gcc/gcc/gcc/ada s-auxdec.adb
