Comment (by slyfox):

 Unfortunately it was not enough for UNREG build.
 Still fails but now generated code is invalid:
 {{{
 /tmp/ghc31859_0/ghc_4.hc:352:5: error:
      error: 'c2l_entry' used but never defined [-Werror]
      IF_(c2l_entry);
          ^
     |

 }}}

 Generated code:

 {{{
 FN_(stg_catch_entry) {
 W_ _c2g;
 _c2h:
 _c2g = R1.w;
 R1.w = *((P_)(_c2g+8));
 Sp[-1] = *((P_)(_c2g+16));
 Sp=Sp-1;
 JMP_((W_)&stg_catchzh);
 }

 const StgWord stg_catch_info[]__attribute__((aligned(8)))= {
 (W_)&stg_catch_entry, 0x2UL, 0x8UL
 };


 IF_(c2l_entry);
 FN_(stg_catchzh) {
 _c2p:
 Sp[-1] = R1.w;
 Sp=Sp-2;
 JMP_((W_)&c2l_entry);
 }
 }}}

 It should have been '''stg_catch_entry''' instead of '''c2l_entry'''.
