Now it seems everything builds fine if I only remove the
"-fno-tree-dominator-opts" flag. However, I see in the SPEC this:
[Q]
# -fno-tree-ccp -fno-tree-dominator-opts to avoid breakage in src/bt_dup.c
# -fno-tree-pre -fno-tree-pta to avoid breakage in src/hash_page.c
CFLAGS="$RPM_OPT_FLAGS -fno-tree-ccp -fno-tree-dominator-opts -fno-tree-pre
-fno-tree-pta"
%ifarch ppc
CFLAGS="$CFLAGS -D_GNU_SOURCE -D_REENTRANT"
%endif
export CFLAGS
[/Q]
So can I safely remove that flag? /me is scared of the consequences.
