[Bug ada/27936] New: gnatbind fails to link on Tru64 UNIX

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

Bootstrapping current mainline with Ada included fails on Tru64 UNIX V5.1B
when linking gnatbind:

system__pure_exceptions_E
collect2: ld returned 1 exit status
make[3]: *** [gnatbind] Error 1

This happens since at least 20060503.

With nm, I find that those symbols are referenced in b_gnat[1b].o, but
defined in s-purexc.o which isn't linked:

b_gnat1.o

system__pure_exceptions_E        | 0000000000000000 | U | 0000000000000000
system__pure_exceptions___elabs  | 0000000000000000 | U | 0000000000000000

b_gnatb.o

system__pure_exceptions_E        | 0000000000000000 | U | 0000000000000000
system__pure_exceptions___elabs  | 0000000000000000 | U | 0000000000000000

s-purexc.o

$system__pure_exceptions___elabs..ng | 0000000000000000 | N | 0000000000000000

Environment:
System: OSF1 bartok V5.1 2650 alpha
Machine: alpha

host: alpha-dec-osf5.1b

How-To-Repeat:
Bootstrap mainline as described above.


------- Comment #1 from ro at techfak dot uni-bielefeld dot de  2006-06-07 18:02 -------
Fix:
Add ada/s-purexc.o to ada/Make-lang.in (GNATBIND_OBJS).

If this is considered the correct fix, I'll submit a proper patch.
