>Environment:
Red Hat Linux 7.1
>Description:
Compiling libstdc++-v3/src, the build got to c++locale.cc
and died with a complaint about invalid opcodes, e.g.

invalid instruction for this architecture; 
needs 68020 or higher -- statement `casl d0,d2,a0@' ignored

See attached file for a cutdown of the log.
>How-To-Repeat:
After building and installing native 3.0.3, I put that
at the front of my PATH and tried an m68k cross compiler.
Specifically, I did:

$SOURCE/configure --prefix $INSTALL
	--target m68k-aout
	--with-gnu-as --with-gnu-ld --with-newlib 
	--enable-languages=c++ --disable-shared 
	--with-headers=$SOURCE/newlib/libc/include"
make
