Re: bootstrapping gnat GCC on amd64

Hi.

After a week off, another update:

I've realised, too late, that I'm using a version of binutils
(2.19) that's incompatible with the system binutils (2.15).
Specifically, assembler code emitted by the native GNAT contains
.cfi_personality directives (and no doubt other things too) that
can't be processed by the system 'as'.

I've got two choices now and would appreciate some advice on
which to take given that I want to produce a FreeBSD port:

  1. Compile binutils-2.15.

  Unfortunately, compiling these as cross-binutils appear to be problematic:

  gmake[3]: Entering directory `/root/memfs/c1-bu-obj/gas'
  gcc -DHAVE_CONFIG_H -I. -I/root/binutils-2.15/gas -I. -D_GNU_SOURCE -I. -I/root/binutils-2.15/gas -I../bfd -I/root/binutils-2.15/gas/config -I/root/binutils-2.15/gas/../include -I/root/binutils-2.15/gas/.. -I/root/binutils-2.15/gas/../bfd -I/root/binutils-2.15/gas/../intl -I../intl -DLOCALEDIR="\"/cross/x86_64/share/locale\""   -W -Wall -Wstrict-prototypes -Wmissing-prototypes -g -O2 -c /root/binutils-2.15/gas/app.c

  gmake[1]: *** [all] Error 2
  gmake[1]: Leaving directory `/root/memfs/c1-bu-obj/gas'
  gmake: *** [all-gas] Error 2

  2. Continue to use binutils-2.19.

  This would appear to require me to create a binutils-2.19 port
  just for the GNAT compiler. Seems like it would be preferable
  to use the system binutils rather than to take this route...
