+Subject: [patch] Fix DWARF-3+ DW_AT_accessibility default assumption
+
+Hi,
+
+GDB regresses on default compiler option -gdwarf-3 on gcc-4.6+ as this gcc
+started to omit DW_AT_accessibility for the default value case.  Normal
+upstream gcc still has -gdwarf-2 default (Fedora uses -gdwarf-3 default).
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
+(There are other regressions to be fixed due to gcc45->gcc46.)
+
+I will check it in in some time.
+
+
+Thanks,
+Jan
