Compiling GCC 4.8.5 on Fedora 25 ( GCC 6.2 )

[Matthew Sellers]

Hi Jonathan -- thanks for the reply.

Are you able to share what options you are using?  I am trying this
with just --enable-languages=c,c++ ( no other options ).  I have also
tried building with most flags from the source toolchain I am trying
to replicate ( Fedora 20 ) via src rpm.  I am also tried on FC24 for
giggles.   All attempts fail with CXXABI errors.


Thanks!
Matt
