Problem when compiling gcc for rtems-4.6 toolchain

[Ian Caddy]

Hi Dominik,

When we built gcc recently, this is the configure line we used (just 
replace m68k-rtems with sparc-rtems):

  ../gcc-3.2.3/configure --target=m68k-rtems --with-gnu-as --with-gnu-ld 
--with-newlib --verbose --enable-threads --enable-languages='c,c++' 
--prefix=/opt/rtems323

Note the with-gnu-as and with-gnu-ld.

I hope this helps.

regards,

Ian Caddy
