Comment 1 Hallvard B Furuseth 2003-03-30 12:16:00 UTC 
Fix:
Don't hard-code ECHON=bsd in gccbug, instead check for bsd vs. sysv echo

Hello,

I can confirm that this problem is still present in gccbug on gcc 3.3 branch and mainline. Could 
you send the patch you included to the gcc-patches list? Thanks,

Dara

Make sure you sent your patch to gcc-patches@gcc.gnu.org.

patch here: <http://gcc.gnu.org/ml/gcc-patches/2003-05/msg02245.html>.
Comment 6 Andrew Pinski 2004-10-18 04:03:50 UTC 
Hmm, this file really comes from GNU GNATS, maybe we should update it from there and you should 
submit the patch to there if it is not already changed.
Comment 7 Andrew Pinski 2004-10-18 04:05:34 UTC 
Just to tell you the GNATs 4.0 regression does not have this patch in it.
