Description Andrew Pinski 2004-06-05 16:54:17 UTC 
IIRC darwin is the last user of NO_IMPLICIT_EXTERN_C.  This PR is just for the progress of the getting rid 
of the use.
Comment 1 Andrew Pinski 2004-06-05 16:54:35 UTC 
Confirmed.

 rid of


Note that NO_IMPLICIT_EXTERN_C is an inverted flag - that is, we want
to get rid of it by turning it *on* universally.

Comment 5 Andrew Pinski 2004-07-08 05:22:11 UTC 
Note I was wrong NetBSD also does not define NO_IMPLICIT_EXTERN_C but I think it is a mistake.
Comment 6 John David Anglin 2004-10-02 20:15:58 UTC 
I believe AIX needs this behavior for assert.h, ctype.h and possibly other
headers.
Comment 7 Hans-Peter Nilsson 2004-12-07 13:18:52 UTC 
Just to mention that arm-elf has the same oversight; missing
NO_IMPLICIT_EXTERN_C.  (The only define of it in config/arm, is in
config/arm/linux-elf.h.)
Comment 8 Geoff Keating 2006-10-03 20:27:42 UTC 
Fixed with <http://gcc.gnu.org/ml/gcc-patches/2006-05/msg01398.html>, queued for 4.3.

Comment 10 Geoff Keating 2006-11-01 05:37:53 UTC 
I can't tell if this bug is fixed.  However, Darwin now has NO_IMPLICIT_EXTERN_C set.
Comment 11 Richard Biener 2008-03-14 16:35:57 UTC 
Whatever.  Reporter please re-open if not fixed.
