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.

Tcl is Lisp on drugs. Using strings instead of S‐expressions for closures is
Evil with one of those gigantic E’s you can find at the beginning of chapters.
