+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.
