We've already made a decision to use C++ when it makes sense. That ship

Yeah, when can I write something as anachronistically futuristic as:
v.qsort ([](auto a, auto b)
{ return int (**(Obj const *const *)a
<=> **(Obj const *const*)b); });
huh?

Re: GCC contribution
Your prochronistic expression is why front ends is developed.
The purpose of the GCC engine is to make anachronistic futuristic code
executable by means of a front-end, not to implement every star-trek
expression.
Why having this pointless conversation, the Titanic has left the port.

Patching the GCC build system to build MPICH and OpenCoarrays
All, Jerry DeLisle, Daniel Celis Garza, and I would greatly appreciate feedback on our approach to patching the GCC build system to build MPICH and OpenCoarrays after it builds gfortran (gfortran requires MPI and OpenCoarrays to support the parallel features of Fortran 2008 and Fortran 2018). A diff of our work relative to the GCC trunk is at http://bit.ly/2pQuzvS. Our steps so far include the following: 1. Jerry wrote an autotools build system for OpenCoarrays (on the OpenCoarrays issue-343-gnu-build branch.) 2. Jerry got MPICH and OpenCoarrays tar balls onto the GCC ftp server. 3. I modified GCC’s contrib/download_prerequisites script to download the tar balls. 4. Daniel edited GCC’s Makefile.def, config.ac, and Makefile.tpl to incorporate MPICH. Our current issue is that the Makefile produced as follows doesn’t create the desired “mpi" directory: git clone -b build-mpich https://github.com/sourceryinstitute/gcc mkdir -p gcc/build cd gcc/build ../configure --disable-bootstrap --enable-languages=fortran whereupon "grep mpi Makefile” only returns comments and an echo statement. Ultimately, our desired sequence is to build gfortran, then build MPICH, and then build OpenCoarrays. All advice is welcome. Damian
