Comment (by Peter_Dyballa@…):

 Trying the patch `std=.patch` allows compilation of `gtest-all.c`. But now
 a new error arrises:

 {{{

 So it's this block of C++ statements that the used Apple GCC 4.2 does not
 understand:

 {{{
    31   #define SCOPED(x) typedef std::unique_ptr<x, ScopedMaybeDelete<x>
 > Scoped ## x
    32
    33   SCOPED(PK11SlotInfo);
    34   SCOPED(SECItem);
    35   SCOPED(PK11SymKey);
    36   SCOPED(SECKEYPublicKey);
    37   SCOPED(SECKEYPrivateKey);
    38   SCOPED(SECAlgorithmID);
    39   SCOPED(CERTSubjectPublicKeyInfo);
    40
    41   #undef SCOPED
 }}}

 I think this means that at least GCC 4.8 has to be used, taking into
 account also the warning from `coreconf/Werror.mk`… (but I am no C++
 expert)
